Richard Oberreuter and his sons, Thomas and Todd, were removing a C.B. radio base antenna from their house when it came into contact with an uninsulated power line carrying electricity to their farm buildings. Richard and Thomas were injured.
The 15-foot aluminum base station antenna was attached atop a 25-foot steel water pipe which was fastened to the north eave of the Oberreuter home. The antenna was installed by plaintiffs during the winter of 1974-75. The antenna was purchased from I-O-TEK, which was owned by Gerald Michel at the time of the sale. Subsequently Michel sold I-O-TEK to Orville Stevens. The power lines involved in the accident were installed on plaintiffs’ property at their request in October, 1973.
The Oberreuter family filed the present action against Orion Industries, Inc., the manufacturer of the antenna; Mid-State Distributing Company and Business Radio Sales and Service, the alleged wholesale distributors of the antenna; and Benton County Electric Cooperative Association (BCECA), the rural electric cooperative which had installed the power line on plaintiffs’ property.
Richard and Thomas Oberreuter sought damages for their personal injuries. Todd Oberreuter, who witnessed the accident, sought damages for negligent infliction of emotional distress. Violet Oberreuter, Richard’s wife, sought damages for loss of consortium. Her claim for negligent infliction of emotional distress was dismissed and the dismissal affirmed on appeal because she was not a witness or bystander to the accident.
See Oberreuter v. Orion Industries, Inc.,
The plaintiffs asserted a product liability claim against manufacturer Orion and alleged wholesalers Mid-State and Business Radio for failure to warn of the danger of electrical shock if the antenna were used near an electrical line. The plaintiffs asserted BCECA was negligent in installing an uninsulated power line, in locating the power line too close to plaintiffs’ house and in failing to warn plaintiffs of possible dangers from the presence of an uninsulated power line situated that close to plaintiffs’ house.
On the first day of trial plaintiffs dismissed their claims against Business Radio. At the close of evidence, the trial court entered a directed verdict in favor of Mid-State, the alleged distributor. The trial court held there was insufficient evidence to establish that Mid-State had supplied the antenna in question to the retailer from whom the plaintiffs had purchased it. The balance of the case went to the jury, which returned a verdict for the remaining defendants finding defendants were not negligent and finding Orion was not liable under strict liability theory. This appeal followed.

Our scope of review on actions at law is on assigned error only. Iowa R.App.P. 4. A jury verdict is binding upon this court
*209
unless the record lacks substantial evidence. Iowa R.App.P. 14(f)(1);
State v. Blair,
II.
Plaintiffs contend the trial court erred in granting a. directed verdict dismissing Mid-State at the close of evidence on the ground plaintiffs had not produced sufficient evidence to establish Mid-State, rather than another wholesaler, had supplied the antenna.
In determining whether a jury question was engendered when a party seeks a directed verdict we apply the same principles as the trial court. We view the evidence in the light most favorable to the nonmoving party, regardless of whether such evidence is contradicted, to determine if reasonable minds could differ on the issue.
Harvey v. Palmer College of Chiropractic,
A directed verdict is appropriate in cases where each element of the claim is not supported by substantial evidence.
Kurth v. Van Horn,
Plaintiffs assert there was substantial evidence Mid-State was the distributor of the antenna in question. Plaintiffs contend there was evidence that only two distributors supplied Orion antennas to I-O-TEK; that Michel testified Mid-State supplied 90 percent of those antennas; and that the records of the other distributor, Business Radio, gave no indication it had supplied the antenna in question to I-O-TEK. However, there is no direct evidence Mid-State distributed the antenna involved in the accident. Plaintiffs admitted all the evidence was circumstantial and that direct evidence was unavailable since relevant Mid-State records had been destroyed some time prior to the accident.
In Iowa, circumstantial evidence may be sufficient to engender a jury question.
Schermer v. Muller,
Plaintiffs state in their brief the following “conclusions seem clear” even if supported by only circumstantial evidence:
Oberreuter purchased the antenna from I-O-TEK. I-O-TEK obtained most of its antennas from Mid-State and a small percentage of those antennas from Business Radio Sales. The owner of Business Radio Sales stated categorically that he had not provided I-O-TEK with this particular antenna. Consequently, the conclusion seems obvious that the antenna involved in this accident came from Mid-State Distributing.
In addition, plaintiffs argue the circumstantial evidence was substantial enough to engender a jury question because I-O-TEK owner Steven’s testimony on cross-examination “is the only evidence that Mid-State did not distribute the antenna.”
However, plaintiffs’ evidence Mid-State distributed the antenna is all based on negative inferences. Plaintiffs contend since there is no positive evidence anyone else distributed the antenna it is *210 therefore proper to conclude Mid-State distributed it. Negative inferences do not necessarily satisfy the burden of positive proof. In the instant case, we find plaintiffs did not produce even a scintilla of positive proof Mid-State distributed the antenna. In addition, on cross-examination Michel, I-O-TEK owner at the time plaintiff purchased the antenna, negated the inferences which formed the basis of plaintiffs’ evidence against Mid-State. Michel testified he did not recall how many distributors he purchased antennas from at the time plaintiffs purchased their antenna. Michel also testified he generally purchased antennas from several distributors, not just the two distributors plaintiffs named in their action, and he testified he was not certain what percentage of the antennas he purchased from Mid-State. Moreover, Michel testified on cross-examination he commingled the antenna inventory and had no records showing either a purchase from Mid-State at the time in question or a sale to plaintiffs. There were only records of purchases from Mid-State after the date of sale claimed by plaintiffs.
We agree with the trial court these facts taken as a whole do not rise above the level of mere speculation or conjecture.

Plaintiffs next contend the trial court erred by excluding evidence of (1) safety standards promulgated by the Consumer Product Safety Commission for warnings on C.B. antennas; and (2) another allegedly similar accident in which a C.B. antenna had come into contact with a power line installed by BCECA.
The trial court has wide discretion in ruling on the admissibility of evidence.
Carter v. Wiese Corp.,
A. Safety Standards. Prior to trial Orion filed a motion in limine seeking to prevent Consumer Product Safety Commission standards enacted in 1978 from being admitted at trial. The 1978 standards required that warnings be placed on all antennas manufactured after February 28, 1978. Plaintiffs had purchased their antenna in 1974. Thus, plaintiffs’ antenna was manufactured at least four years prior to the 1978 manufacturing standards.
The trial court sustained Orion’s motion in limine stating the promulgation of standards four years after manufacture was not relevant to the issues in the instant case. The trial court based its decision on
Alter v. Rodgers Machinery Manufacturing Co.,
*211
Plaintiffs argue the safety standards were relevant on the issue of “defectiveness of the product.”
See Dambacher v. Mallis,
However, plaintiffs’ argument places it squarely within the purview of
Aller
and other defective design cases.
See Daberko v. Heil, Co.,
We determine the trial court was correct by refusing to admit the 1978 Consumer Product Safety Commission Standards.
B. Similar Accident. During the testimony of BCECA employee Melbert Beiber, who determined where the power line was to be located on plaintiffs’ property, plain-. tiffs attempted to introduce evidence BCE-CA officials discussed reports of an accident which occurred when someone removing some kind of antenna was killed after bringing the antenna into contact with a live power line. Allegedly that accident occurred prior to the accident in which plaintiffs were injured. BCECA objected to admission of evidence regarding the pri- or accident. The trial court sustained BCE-CA’s objection. The trial court found the evidence was irrelevant, inadmissible under Iowa R.Evid. 403 and inadmissible under
Eickelberg v. Deere & Co.,
Evidence of similar accidents is admissible in negligence cases to show a hazard and knowledge thereof.
Madison v. Colby,
The person in the alleged “similar accident” was killed when he touched an antenna with a live power line installed by BCE-CA. In their brief plaintiffs argue such evidence should not be excluded merely because the resulting injuries were not of the same severity:
[I]f a hazardous condition of a sidewalk caused one person to fracture a leg and a second person to suffer a concussion, the difference in their respective injuries is irrelevant.
Plaintiffs also cite
Greyhound Lines, Inc. v. Miller,
In
Greyhound,
however, the court held evidence of prior accidents on the
same
premises was relevant to show the owner’s knowledge of the dangerous conditions.
Greyhound,
We therefore reject plaintiffs’ contentions on appeal and affirm the trial court on all counts.
AFFIRMED.
