Bassam E. Marji appeals from a judgment of conviction entered on April 17,1997, in the United States District Court for the Northern District of New York (Scullin, J.) following a jury trial. The district court sentenced the defendant to 51 months’ imprisonment on various charges, including: attempting to destroy a building by arson, in violation of 18 U.S.C. § 844(i); committing insurance fraud through the use of the mails, in violation of 18 U.S.C. § 1341; conspiring to commit mail fraud, in violation of 18 U.S.C. § 371; and using fire to commit mail fraud, in violation of 18 U.S.C. § 844(h). The defendant’s offense level for these crimes was calculated under § 2K1.4(a)(l) of the Sentencing Guidelines because the district court determined that he had knowingly created a serious risk of bodily injury or death to others and because the arson involved the destruction of a dwelling. The district court then sentenced the defendant to an additional 60 months’ imprisonment under 18 U.S.C. § 844(h) (to run consecutively to the 51 months) for the commission of a felony through the use of fire. The defendant was also ordered to pay $21,182.26 in restitution.
Defendant’s conviction arose out of the events leading up to and following his decision to set fire to a flower shop in Canastota, New York on October 2, 1993, so that he and his co-owner could collect insurance proceeds for the resulting damages.
On appeal, the defendant attacks his conviction and sentence on a number of grounds. First, he claims that the district court erroneously allowed a juror to serve despite the fact that the juror was a volunteer fireman in the county in which the fire took place. Second, he argues that the admission of expert testimony regarding the alerting by an accel-erant-sniffing canine to traces of accelerant was error. Third, he claims that the district judge impermissibly interfered with his attorney’s cross-examination of a key government witness and with the direct examination of the defense’s expert witness. Fourth, he claims that there was insufficient evidence to convict him. Finally, he challenges the length of his sentence.
I.
The first four of the defendant’s arguments can be dealt with summarily.
A.
The decision of the district judge not to dismiss for cause the juror at issue lay well within the court’s discretion. It is well settled that a juror not shown to have actual bias is not excludable merely because he or she is a member of a particular occupation or even of law enforcement.
See United States v. Wood,
B.
Under
Daubert v. Merrell Dow Pharmaceuticals, Inc.,
We conclude that the trial judge did not abuse his broad discretion under Daubert in admitting the testimony. We note further that, even if we were to assume arg-uendo that the district judge’s decision to allow this expert testimony was erroneous, there was substantial additional evidence offered at trial demonstrating that an accelerant was used by the defendant to start the fire. Thus, any error in admitting the dog-sniff testimony would have been manifestly harmless.
C.
In general, the extent of cross examination to be permitted lies within the discretion of the district judge.
See
Fed. R.Evid. 611(a) (granting trial judge broad discretion to control witness examination). In the case before us, there is no evidence of any bias on the part of the judge or that the defendant was denied a fair trial. We conclude that the judge’s actions in limiting defense counsel’s attempt to impeach a key government witness by introducing wholly unrelated events did not in any way constitute an abuse of discretion.
See United States v. Tocco,
Similarly, we find no merit in the defendant’s claim that the trial judge improvidently interfered with the defense’s direct examination of its expert witness. The judge was well within his powers in keeping the witness from testifying with respect to highly questionable facts as to which the witness had no direct knowledge.
See United States v. Locascio,
D.
A convicted defendant bears a “very heavy burden” in challenging the sufficiency of the evidence.
United States v. Gonzalez,
II.
The questions raised by the defendant with respect to his sentence are not more complicated than those with which we have just dealt. He does, however, raise two issues that have not been previously addressed by this Court.
A.
First, the defendant argues that the district court improperly compiled his base offense level for sentencing, under § 2K1.4(a)(l) of the Sentencing Guidelines, when it determined that the defendant had knowingly created a substantial risk of death or serious bodily harm to others and that the fire involved the destruction of a dwelling.
See
U.S. Sentencing Guidelines Manual § 2K1.4(a)(l) (1996).

The district court ex
*64
pressly found that the defendant was aware that there were occupied apartments above the flower shop — indeed, the court noted that he had previously rented one of these apartments. The trial court’s findings of fact are not to be disturbed unless they are clearly erroneous. And we cannot say that the district judge’s determination was error, let alone clear error.
See United States v. Molina,
The district court also determined that the defendant (a) used an accelerant to start the fire, (b) set the fire in a building that he knew included occupied apartment dwellings, and (c) set the fire at 7:00 p.m. on a Saturday evening, a time when the neighboring pizza parlor was very likely to be filled with customers. Given this host of factors, it is difficult to imagine how the defendant could not have known that his actions would put many people at grave risk of serious injury or, possibly, death. Under the circumstances, we conclude that the district court’s determination that the defendant “knowingly” created a serious risk of bodily injury or death was not erroneous.
B.
The defendant also challenges the district court’s imposition of a 60-month sentence to run consecutively to the longest underlying sentence that defendant received as a result of the arson that he committed. Under 18 U.S.C. § 844(h), a person who uses fire or explosives to commit a felony (such as mail fraud) is subject to an additional mandatory, and consecutive, sentence of five to fifteen years. The defendant argues that this term runs only from the end of the sentence assessed for the underlying predicate felony that triggered the application of § 844(h) — and not from the end of the longest sentence imposed for any of the felonies that arose out of the same conviction and stemmed from the same series of events.
18 U.S.C. § 844(h) reads, in pertinent part: Whoever—
(1) uses fire or an explosive to commit any felony which may be prosecuted in a court of the United States, or
(2) carries an explosive during the commission of any felony which may be prosecuted in a court of the United States,
including a felony which provides for an enhanced punishment if committed by the use of a deadly or dangerous weapon or device shall, in addition to the punishment provided for such felony, be sentenced to imprisonment for 5 years but not more than 15 years.... Notwithstanding any other provision of law ... the term of imprisonment imposed under this subsection [shall not] run concurrently with any other term of imprisonment including that imposed for the felony in which the explosive was used or carried.
18 U.S.C. § 844(h) (1996). 2
The defendant argues that the language barring the concurrent running of the additional sentence with “any other term of imprisonment including that imposed for the felony in which the explosive was used or earned,’’ (emphasis added), limits the application of the section to § 844(h)(2) crimes, and does not bar concurrent sentences as to crimes, such as some of the defendant’s, that are covered by § 844(h)(1).
We conclude, however, that the most reasonable construction of the statute is that which was adopted by the district court and also by those of our sister circuits that have addressed the question.
See United States v. Riggio,

We have considered all of Marji’s arguments and found them to be without merit. Accordingly, we affirm the judgment of the district court.
Notes
. Section 2K1.4(a)(1) provides that the base offense level for sentencing should be 24 "if the *64 offense (A) created a substantial risk of death or serious bodily injury to any person other than a participant in the offense, and that risk was created knowingly; or (B) involved the destruction or attempted destruction of a dwelling." Id.
. This section was amended in 1996, when Congress increased the punishments available under the statute. See 18 U.S.C. § 844(h) (West Supp. 1998).
