# §1926.907. Use of safety fuse.

- (a) Safety fuse shall only be used where sources of extraneous electricity make the use of electric blasting caps dangerous. The use of a fuse that has been hammered or injured in any way shall be forbidden.
- (b) The hanging of a fuse on nails or other projections which will cause a sharp bend to be formed in the fuse is prohibited.
- (c) Before capping safety fuse, a short length shall be cut from the end of the supply reel so as to assure a fresh cut end in each blasting cap.
- (d) Only a cap crimper of approved design shall be used for attaching blasting caps to safety fuse. Crimpers shall be kept in good repair and accessible for use.
- (e) No unused cap or short capped fuse shall be placed in any hole to be blasted; such unused detonators shall be removed from the working place and destroyed.
- (f) No fuse shall be capped, or primers made up, in any magazine or near any possible source of ignition.
- (g) No one shall be permitted to carry detonators or primers of any kind on his person.
- (h) The minimum length of safety fuse to be used in blasting shall be as required by State law, but shall not be less than 30 inches.
- (i) At least two men shall be present when multiple cap and fuse blasting is done by hand lighting methods.
- (j) Not more than 12 fuses shall be lighted by each blaster when hand lighting devices are used. However, when two or more safety fuses in a group are lighted as one by means of igniter cord, or other similar fuse-lighting devices, they may be considered as one fuse.
- (k) The so-called “drop fuse” method of dropping or pushing a primer or any explosive with a lighted fuse attached is forbidden.
- (l) Cap and fuse shall not be used for firing mudcap charges unless charges are separated sufficiently to prevent one charge from dislodging other shots in the blast.
- (m) When blasting with safety fuses, consideration shall be given to the length and burning rate of the fuse. Sufficient time, with a margin of safety, shall always be provided for the blaster to reach a place of safety.
