*545 MEMORANDUM AND ORDER
Pеnding before the court is Defendant Terex Teleleet, Inc.’s (“Terex”), Motion for Summary Judgment (# 51). Terex seeks summary judgment on Plaintiff Raymond W. Whitmire, Sr.’s (“Whitmire”), claims of strict products liability, negligence, and breach of express and/or implied warranties of safety arising from injuries he allegedly sustained in an accident involving a digger derrick truck 1 designed, manufactured, and marketed by Terex. Having reviewed the pending motion, the submissions of the parties, the pleadings, and the applicable law, the court is of the opinion that summary judgment should be granted in part and denied in part.
I. Background
On or about June 5, 2001, Whitmire, a heavy equipment operator, was operating a Terex Teleleet Commander 4045 Model Digger Derrick (“digger derrick”) “mounted on the chassis of a heavy duty pickup truck which requires a commercial driver’s license to operate.” Whitmire had workеd with and operated the digger derrick for approximately one week prior to the incident in question. On the day of the accident, Whitmire, his brother, L.D. Whit-mire, and his son, Raymond Whitmire, Jr. (“Whitmire, Jr.”), were working with a group of employees from L.E. Myers Co. (“Myers”), installing new utility poles and lines along a residential street in San Antonio, Texas.
After arriving at the work site, Whit-mire climbed up into the operator’s chair of the digger derrick to begin operating the equipment. Before starting work, a co-worker notified Whitmire that an electrical pole down the street was uneven and needed to be straightened with the digger derrick. Instead of descending from the operator’s chair and getting into the truck, Whitmire remained in the chair and, because the rest of the crew was elsewhere, instructed Whitmire, Jr., who had never driven the truck and did not have a commercial driver’s license, to back the truck down the road to the uneven pole. Whit-mire, Jr., complied and drove the truck in reverse while Whitmire remained in the operator’s chair.
As he proceeded in reverse, Whitmire, Jr., inadvertently drove the truck toward some tree limbs, one of which struck Whit-mire in the mid-back area and pushed him forward out of his seat. According to Whitmire, he “stepped out and got [his] foot on the step” and “swung around to get on the side of the truck to get away from the limb.” When he reached for a handhold, he discovered that there was nothing for him to grab. After losing his balance, Whitmire fell out of the chair and plunged twelve feet to the ground, allegedly suffering significant bodily injuries, including a broken neck and a broken hand. In contrast, Terex claims that Whitmire and his crew violated basic safety rules that led to Whitmire’s being struck by a branch, which knockеd him out of the operator’s chair and onto the ground. As a consequence, Terex argues, Whitmire “cannot prove that he would not have suffered his injuries had there been additional ‘grab-rails’ or an intermediate step on the digger derrick in question.”
Whitmire, a resident of Mauriceville, Orange County, Texas, instituted this diversity action, on January 24, 2003, asserting products liability claims against Terex, a wholly-owned subsidiary of Terex Utilities. Terex is incorporated in the State of Delaware and maintains its principal place of business in Watertown, *546 South Dakota. Zurich American Insurance Company, Myers’s workers’ compensation carrier, was added to the lawsuit as an additional defendant due to a potential subrogation interest it may have in this case. In his complaint, Whitmire alleges that the digger derrick, “as designed, manufactured and sold by Defendant, had inadequate and unsafe means of egress and ingress, and inadequate guarding or protective material, which was a proximate cause of injury to Plaintiff.” In addition, Whitmire asserts that the digger derrick was “unreasonably dangerous and defectively designed, marketed and sold (including inadequate or defective warnings and instructions), and reached Plaintiff in substantially the same condition in which it left Defendant’s custody, which was a producing cause of the occurrence in question and Plaintiffs injuries and damages.”
Whitmire also alleges that Terex was negligent in the design, manufacture, marketing, and sale of the digger derrick, which was a proximate cause of Whitmire’s injuries and damages. Lastly, Whitmire claims that Terex breached express and/or implied warranties of safety with respect to the digger derrick, which was a proximate cause of Whitmire’s injuries and damages. As a result of Terex’s allegedly tortious conduct, Whitmire is seeking damages for present and future bodily injuries, including loss of earnings and earning capacity, medical and hospitalization expenses, physical impairment, physical pain, and mental anguish.
On November 12, 2004, Terex filed its motion for summary judgment, claiming that neither Whitmire nor Zurich can “prove the causation elements of either their claim of defective design or their negligence cause of action and because neither Plaintiff nor Intervenor can prove the safer alternative design element of their strict product liability claim or that Defendants breached any duty to them as is required to show negligence.” Specifically, Terex argues that Whitmire has adduced no evidence to show that any design defect was a producing cause of his injuries or that the digger derrick at issue was unreasonably dangerous. With respect to his negligence claim, Terex states that Whitmire “has no evidence that it was reasonably foreseeable to Terex-Telelect, Inc. that Plaintiff and his crew members would abandon common sense and violate basic safety rules and that the digger derrick would be backed into a tree knocking Mr. Whitmire out of the operator’s chair.”
II. Analysis
A. Summary Judgment Standard
Rule 56(c) of the Federal Rules of Civil Procedure provides that summary judgment “shall be rendered forthwith if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to judgment as a matter of law.” Fed. R. Civ. P. 56(c). The party seeking summary judgment bears the initial burden of informing the court of the basis for its mоtion and identifying those portions of the pleadings, depositions, answers to interrogatories, admissions on file, and affidavits, if any, which it believes demonstrate the absence of a genuine issue of material fact.
See Celotex Corp. v. Catrett,
*547
“A fact is
‘material’
if it
‘might affect
the outcome of the suit under governing law.’ ”
Bazan v. Hidalgo County,
Once a proper motion has been made, the nonmoving party may not rest upon mere allegations or denials in the pleadings but must present affirmative evidence, setting forth specific facts, to show the existence of a genuine issue for trial.
See Celotex Corp.,
Nevertheless, “ ‘only
reasonable
inferences can be drawn from the evidence in favor of the nonmoving party.’ ”
Eastman Kodak Co. v. Image Tech. Servs., Inc.,
Summary judgment is mandated if the nonmovant fails to make a showing sufficient to establish the existence of an element essential to his case on which he bears the burden of proof at trial.
See Nebraska v. Wyoming,
B. Abandonment of Claims
In his response to the summary judgment motion, Whitmire does not address his causes of action for manufacturing and marketing defects or breach of express and/or implied warranties of safety and appears to have abandoned them. Indeed, because he did not raise or brief these issues in his responsive brief, any claims by Whitmire relying on these theories have been waived and are no longer at issue.
See Bursztajn v. United States,
C. Products Liability — Texas Law
In asserting his products liability claims, Whitmire relies on Restatement (Third) of Torts: Products Liability §§ 1-3, complaining of the allegedly defective design of the digger derrick. The relevant sections of the Restatement provide as follows:
§ 1. LIABILITY OF COMMERCIAL SELLER OR DISTRIBUTOR FOR HARM CAUSED BY DEFECTIVE PRODUCTS
One engaged in the business of selling or otherwise distributing products who sells or distributes a defective product is subject to liability for harm to persons or property caused by the defect.
Restatement (Third) of Torts: PROducts Liability § 1 (1998).
§ 2. CATEGORIES OF PRODUCT DEFECT
A product is defective when, at the time of sale or distribution, it contains a manufacturing defect, is defective in design, or is defective because of inadequate instructions or warnings. A product:
(a) contains a manufacturing defect when the product departs from its intended design evеn though all possi *549 ble care was exercised in the preparation and marketing of the product;
(b) is defective in design when the foreseeable risks of harm posed by the product could have been reduced or avoided by the adoption of a reasonable alternative design by the seller or other distributor, or a predecessor in the commercial chain of distribution, and the omission of the alternative design renders the product not reasonably safe;
(c) is defective because of inadequate instructions or warnings when the foreseeable risks of harm posed by the product could have been reduced or avoided by the provision of reasonable instructions or warnings by the seller or other distributor, or a predecessor in the commercial chain of distribution, and the omission of the instructions or warnings renders the product not reasonably safe.
Id. at § 2.
§ 3. CIRCUMSTANTIAL EVIDENCE SUPPORTING INFERENCE OF PRODUCT DEFECT
It may be inferred that the harm sustained by the plaintiff was caused by a product defect existing at the time of sale or distribution, without proof of a specific defect, when the incident that harmed the plaintiff:
(a) was of a kind that ordinarily occurs as a result of product defect; and
(b) was not, in the particular case, solely the result of causes other than product defect existing at the time of sale or distribution.
Id. at § 3.
Products liability claims in Texas fall into three categories: design defect, manufacturing defect, and marketing defect, also referred to as warning defect.
See American Tobacco Co. v. Grinnell,
1. Design Defect
Whitmire alleges that the digger derrick was unreasonably dangerous and that a safer alternative design existed. Specifically, Whitmire contends that Terex failed to equip its digger derrick with adequate access to and from the operator’s chair, including a lack of handholds or handrails and an intermediate step, and failed to shield adequately the operator working in that position.
“The duty to design a safe product is ‘an obligation imposed by law.’ ”
Grinnell,
Under Texas law, “liability for a design defect may attach even if the defect is apparеnt.”
Grinnell,
By statute in Texas, “[a] plaintiff must prove that there is a safer alternative design in order to recover under a design defect theory.”
Sanchez,
(a) In a products liability action in which a claimant alleges a design defect, the burden is on the claimant to prove by a preponderance of the evidence that:
(1) there was a safer alternative design; and
(2) the defect was a producing cause of the personal injury, property damage, or death for which the claimant seeks recovery.
(b) In this section, “safer alternative design” means a product design other than the one actually used that in reasonable probability:
(1) would have prevented or significantly reduced the risk of the claimant’s personal injury, property damage, or death without substantially impairing the product’s utility; and
(2) was economically and technologically feasible at the time the product left the control of the manufacturer or seller by the application of existing or reаsonably achievable scientific knowledge.

Hernandez, 2
S.W.3d at 256 (quoting
Grinnell,
Terex argues that Whitmire has no evidence that the digger derrick, by lacking “grab-rails” or an intermediate step, was unreasonably dangerous. Terex asserts that the digger derrick “at the time of this accident was in a condition which was contemplated by the ordinary purchasers and users of such a product.” In addition, Terex claims that Whitmire has failed to produce evidence that a safer alternative design existed at the time the digger derrick was designed and manufactured. Specifically, Terex contends that Whitmire “cannot prove with reasonable probability that his injuries would not have occurred or that the risk of such injuries would have been significantly reduced with a different design.” Terex argues that the lack of testing and evidence “from the field” prevents Whitmire from establishing that the addition of “grab-rails” and/or an intermediate step would have constituted a safer alternative design.
In responsе, Whitmire alleges that “[a] safer alternative designed existed: either a vertical grab rail or an intermediate step, or both.” Whitmire also submits evidence that a digger derrick existed with a cab or other device that shielded the operator in the cab. According to Whitmire, “[n]one of the devices are complicated technical or mechanical devices, and could have easily been added to the product by defendant.” In support of his contention, Whitmire relies on the affidavit of Don Reichert (“Reichert”), a professional, mechanical engineer, who is familiar with digger derricks.
According to Reichert, “[t]he control station access [on the product in question] has no effective grab rails or handrails on the access face to enable the climber to achieve and maintain thе required ‘three point contact.’ ” “Three-point contact,” according to Reichert, refers to three-point support (ie., one hand and two feet, or two hands and one foot) while ascending or descending the access system. Reichert also opines that “[t]he access/egress means on the Terex Telelect 4045 Digger Derrick is unsafe and non-conforming to the recommendations, standards, and industry practice at the time of the manufacture and sale.” In reference to the digger derrick at issue, Reichert states:
This step height exceeds the recommended height of approximately 12 inches found in virtually every ladder-rung-spacing standard practice. The simple addition of a step attached to the floor of the control station and midway below the 25-inch floor height is a safer design alternative.
i}c ‡ % #
*552 Providing continuous vertically oriented grab rails on each side of the control station entrance is a safer alternative to the hand grabs located on the top and front of the C4045 control console. The forward grab rails should extend at least from the top of the console to the lower intermediate step, and at the top, curve forward then around the control console. The rear hand grab should extend from a height above the top of the seat arm rest, and extend behind the seat to the maximum height of the unit. The feasibility of this safer design is demonstrated by several examples of user-modified machines, competitor machines and current specified machines purchased by large utilities.
Attached to his response, Whitmire provides photographs of models that include the prоposed safer alternative design. He maintains that the defect of not having grab rails and/or an intermediate step on the digger derrick was a producing cause of his injuries.
Whitmire also relies on the affidavit of George Greene, Jr. (“Greene”), a professional, mechanical engineer, who worked in private industry as a design engineer and was responsible for new product design. According to Greene, the operator’s chair for the digger derrick at issue was positioned twelve feet above ground, which constitutes a serious hazard to the operator should he slip or otherwise be “dislodged from his perch.” Greene agrees with Reichert that the digger derrick is “not equipped with a safe means of egress or ingress from the ground to the operator’s seat.” Furthermore, among other findings, Greene notes that “[n]о warnings are provided for the truck driver or the digger derrick operator which forbids the operator from remaining at this work station during movement of the vehicle.” He also points out that “[sjuitable hand holds, railings, ladders or steps were not provided by the manufacturers to allow the operator to safely and quickly ingress and egress the equipment.” Specifically, he states that the digger derrick was defective and unreasonably dangerous due to:
(a) Lack of adequate means to quickly and safely ascend and descend from the operator’s seat to the ground.
(b) Failure to warn the truck driver and operator as to the prohibition of the equipment operator remaining at his station during movement of the vehicle.
Whitmire further points to the testimony of Terex’s corporate representative, James Olson (“Olson”), who testified as follows:
Q. Would it have been technologically feasible for Terex, at the time that it manufactured and sold the digger derrick in 2, to have equipped the digger derrick in 2 with railing such as we see in Exhibit 3? Just from the standpoint of the physics and the mechanics and the technology, would it have been feasible?
A. Yes.
******
Q. Would you agree that at the time that Terex manufactured and sold the digger derrick in Exhibit 2, that it would have been economically feasible to add the type of railing to the digger derrick in Exhibit 2 as we see in Exhibit 3, just from the standpoint of dollars and cents?
A. Yes, it could have been added.
In addition to proffering photographs of other types of digger derricks, which have incorporated a handrail and/or step system, Whitmire presents excerpts from professional literature addressing equipment safety. Whitmire provides a copy of an article from The Nаtional Safety Council’s *553 Accident Prevention Manual for Business and Industry, which recommends:
Guarding, Safety Devices, Platforms, and Means of Access
Install platforms, footwalks, steps, ladders, handholds, guardrails, and toe-boards on all equipment where they are needed to provide safe access. Provide suitable floors or platforms, surfaced with slip-resistant material, for all equipment operators.
Operators of equipment should be protected against the elements, falling objects, swinging loads, and similar hazards. Be sure that windows in cabs or enclosures on equipment are made of safety glass and kept in good repair at all times.
Whitmire also provides the United States Army Corps of Engineers’ Safety and Health Requirements Manual, which mandates that “ ‘[s]afe access shall be provided to all work areas.’ ” Furthermore, Whit-mire includes a comment from Roland Blake, head of the Bureau of Safety Standards, who writes that “[failure to provide for safe access to every point to which men must go, such as cranes, and the tops of boilers and machines, is responsible for many falls.” Moreover, Whitmire submits guidelines from the American Society of Safety Engineers, which state:
Those companies who make material handling or access equipment are at risk if they have not considered fall hazards and escape needs from buckets, platforms, crane cabs, scaffolds, and during erection and maintenance procedures.
* * * * * *
Lack of means for escape from these high work stations means that, in an emergency, the workers could be trapped. For example, a slow-to-respond bucket truck could be a problem if a swarm of bees attacks an elevated operator and causes him to jump. The manufacturers should be able to address this type of prоblem, once they become aware of even a single occurrence or believe the scenario may occur.
Finally, Reichert points out that “The Society of Automotive Engineers J185 Standard which is applicable to this case, states that ‘all Access Systems shall ... permit and, by proper placement of components, promote achievement of three-point support while ascending or descending the access system when more than one meter above the ground.’ ”
Taken together, the evidence submitted by Whitmire in support of his design defect claim creates a fact issue as to whether the digger derrick was defective in its design and, therefore, unreasonably dangerous. The testimony submitted by Whitmire’s experts and Terex’s corporate representative, along with the professional literature cited, raise genuine issues of material fact as to whether the digger derrick in this case was unreasonably dangerous and whether a safer alternative design, which would have prevented or significantly reduced the risk of Whit-mire’s injuries without substantially impairing the product’s utility, was available. Furthermore, a fact issue exists concerning whether such design was economically and technologically feasible at the time it left the manufacturer or seller.
2. Causation — Producing Cause
In its motion, Terex argues that Whit-mire cannot prove causation with respect to his design defect claim. Specifically, Terex states “[t]o hold Terex-Telelect, Inc. responsible for his damages, Plaintiff must prove that Terex-Telelect, Inc.’s action or its allegedly defective product caused those damages.” Terex alleges that Whit-mire has no evidеnce that the allegedly *554 defective design of the digger derrick was a producing cause of his injuries.
“Under Texas law, causation generally is a question of fact for the jury.”
Flock,
In Texas, a showing of producing cause is an essential element for recovery in a products liability case.
See Flock,
Terex argues that Whitmire “simply has no evidence to prove that any alleged lack of vertical ‘grab-rails’ or an intermediate step was a producing cause of his injuries.” Terex claims that Whitmire’s testimony, along with his son’s testimony, show thаt Whitmire was knocked from the operator’s chair to the ground by the force of the truck being backed up into the tree limb. Terex asserts that Whitmire cannot prove that he would not have suffered his injuries had there been additional “grab-rails” or an intermediate step on the digger derrick. In addition, Terex contends that the “true cause of Plaintiffs injuries was his and his crew’s failure to keep a proper lookout while an inexperienced driver without the proper license to operate the digger derrick drove it in reverse with Plaintiff twelve feet up in the operator’s chair instead of in the cab of the truck.”
In response, Whitmire argues that there is sufficient evidence to demonstrate that the defective condition of the digger derrick was a producing cause of his injury. At deposition, Whitmire testified:
Q. So, the way it sounds like it happened to me, then is that you were watching the ground to the sides of you and watching Ray, Jr. as he was backing this thing up five to ten miles an hour.
*555 A. Right.
Q. And all of a sudden you felt the tree limb in your back. Is that right?
A. Yes, sir.
Q. Then what happened?
A. I got his attention, tried to get him to stop the truck; and by the — as that limb hit me in the back, it kind of pushed me forward. It was — and I had to get — had to get out from under it because it was a big enough limb that — that it was not one that would just scratch you up. I felt like it would hurt my back or maybe could be worse. So, as it bent me over, I tried — -I climbed out of the seat; and as I was stepping around the end of the truck trying to grab ahold of something, I — that’s when I lost my balance.
❖ sfc
Q. Okay. Tell me again how you moved when you felt that tree limb hit you in the back.
A. As the limb hit me in the back, it pushed me forward.
Q. Did it push you forward out of the seat?
A. Pushing me forward up out of the seat.
Q. Okay.
A. I — as it rolled me, I kind of — I stepped out and got my foot on the step.
Q. Okay.
A. And then I swung around to get on the side of the truck to get away from the limb. There’s nothing there. I mean, it’s just boom— boom and digger, you know, the auger.
Q. Uh-huh.
A. That’s all that’s there. I reached for something. There’s nothing there.
Whitmire further elaborated:
Q. Do you think there’s anything else that my client did that caused this accident?
A. I’m not an engineer, so I don’t know how they — the safety — I just know it wasn’t safe far as the ability to hold on to something, to get your hands physically on something, because there’s no — there’s no railing; there’s no tie-off positions or anything on this — on these equipment — pieces of equipment.
‡ ‡ H* ‡ ‡
A. It needed — needed to be safer, and it’s not safe as far as the operator is not protected completely in that cab, in that seat.
Q. What else should have been there to protect the operator?
A. They have — even small, like, mowers have rollover protection and have a — basically a cage or a cab setting above you to keep you from — when limbs — for limbs, for that — for that certain purpose, for limbs coming into — you know, when you run in — get close to limbs.
When asked why he was suing Terex, Whitmire replied:
A. Because of the safety factor of the truck. I felt like if it was safer — if it had hand holds where I could have got — hold on to, climb up on or actually physically held on to, I might not be — you know, I wouldn’t be hurt. I wouldn’t have hurt myself. I’ve been around this equipment a long time, and it’s — you talk about this kind of stuff when you’re working during the day, the process of things that aren’t — you don’t
*556 think is right, this or that, especially if you’re the one that’s having to climb up and down or in or out of a piece of equipment. And climbing up and down that makes it pretty bad because there’s no place to— you’re at risk every time you climb up there to get in that seat to sit down.
According to Whitmire, a jury could reasonably infer from his testimony that additional handrails or an intermediate step would have permitted him to exit the operator’s chair without falling and sustaining injuries. In addition, he alleges that a jury could reasonably conclude that the absence of additional shielding and/or additional railing and/or an intermediate step was a producing cause of his injuries. In support of his argument, Whitmire references Reichert’s report, which states that the “[ajbsence of convenient, effective grab rails and an intermediate step clearly were producing causes of the personal injury suffered by Mr. Whitmire.” Furthermore, Whitmire contends that Terex’s contention that Whitmire was solely or contributorily negligent is a question of fact which should be submitted to the jury as part of a comparative fault analysis.
Based on the record currently before the court, the circumstances of this case appear to be consistent with either of the сompeting causal theories, as espoused by Terex and Whitmire. Terex argues that Whitmire’s injuries would not have been prevented even if there were additional “grab-rails” and/or an intermediate step because the force of the tree limb pushed him out of his chair and onto the ground. Whitmire counters that, if he had been provided additional “grab-rails” or an intermediate step, he could have safely exited the chair without falling to the ground, discounting the notion that the tree limb knocked him directly to the ground. In this situation, because one factual scenario appears no more probable than the other, neither can be inferred definitively at this juncture.
See Flock,
D. Negligence
Whitmire also asserts that Terex breached its duty to design a safe product. Specifically, Whitmire states that Terex was “negligent in the design, manufacture, marketing and sale (including inadequate warnings and instruction) of the product in question, which was a proximate cause of the occurrence in question and Plaintiffs injuries and damages.” Under Texas law, a negligence claim consists of four essential elements: (1) a legal duty owed to the plaintiff by the defendant; (2) a breach of that duty; (3) an actual injury to the plaintiff; and (4) a showing that the breach was the proximate cause of the injury.
See Ford v. Cimarron Ins. Co.,
*557 1. Duty
The first inquiry addressed in all negligence cases is whether a duty was owed to the plaintiff by the defendant.
See Ford,
A seller’s duty to design a safe product is an obligation imposed by law.
See Robins,
2. Proximate Cause
Terex asserts that Whitmire cannot recover on his negligence claim because he fails to establish that the lack of “grab-rails” or an intermediate step was a proximate cause of the accident or his damages. Terex states that in order for Whitmirе to recover, he “must show not only that such acts and omissions were a cause-in-fact of the accident and damages, a burden which it has been shown he cannot meet, but also that the accident was reasonably foreseeable.” Terex argues that Whitmire has no evidence that it was reasonably foreseeable to Terex that 'Whitmire and his fellow workers “would abandon common sense and violate basic safety rules and that the digger derrick would be backed into a tree knocking Mr. Whitmire out of the operator’s chair.”
In Texas, negligence requires a showing of proximate cause.
See Union
*558
Pump Co.,
“Foreseeability means that a person of ordinary intelligence should have anticipated the dangers that his negligence created.”
Gutierrez,
Proximate cause is usually a mixed question of law and faсt for the jury to determine.
See Cherry v. Texas Dep’t of Crim. Justice,
With respect to the cause-in-fact element, Whitmire’s deposition testimony creates an issue of fact as to whether Terex’s failure to provide “grab-rails” and/or an intermediate step was a substantial factor in bringing about Whitmire’s injuries and without which no harm would have occurred. According to Whitmire, had there been additional handrails or “grab-rails” and/or an intermediate step, he could have kept his balance and been able to exit the chair safely after being hit by the tree limb. Thus, Whitmire adduces sufficient evidence to satisfy the cause-in-fact element of proximate cause.
Moreover, Whitmire presents sufficient evidence to establish the foreseeability element of proximate cause. In light of the testimony proffered by Whitmire, a person of ordinary intelligence could have anticipated the danger created by Terex’s failure to provide “grab-rails” and/or an intermediate step on the equipment in question.
See Green v. City of Friendswood,
Construing the evidence in the light most favorable to the non-moving party, reasonable persons could differ in their conclusions. See id. Here, Whitmire’s testimony, when combined with the experts’ affidavits and professional literature, has created critical fact issues as to whether Terex breached its duty to provide a safe product and whether such breach proximately caused Whitmire’s injuries. Therefore, with regard to Whitmire’s negligence claim, summary judgment is not warranted.
III. Conclusion
Under these circumstances, Whitmire has presented sufficient evidence to raise material issues of fact as to whether the digger derrick, manufactured by Terex, was defectively designed and unreasonably dangerous, and thereby constituted a producing cause of Whitmire’s injuries. Whit-mire has also adduced adequate evidence tо create a fact issue as to whether Terex was negligent in the design of the digger derrick and whether such negligence was a proximate cause of Whitmire’s injuries.
*560 Accordingly, Terex’s motion for summary judgment is granted in part and denied in part. Whitmire has abandoned his claims asserting manufacturing and marketing defects as well as breach of express and/or implied warranties of safety, rendering summary judgment appropriate as to those claims. Whitmire, however, may proceed to trial against Terex on his claims of strict products liability and negligence stemming from the design of the digger derrick.
PARTIAL SUMMARY JUDGMENT
In accordance with the court’s Memorandum and Order dated May 5, 2005, summary judgment is rendered in favor of Defendant Terex Telelect, Inc., with respect to Plaintiff Raymond W. Whitmire, Sr.’s, manufacturing and marketing defect claims and his breach of express and/or implied warranties of safety claims.
