The Sweet 16 of BSA Safety describe the measures we should use at all Scouting activities. The fifth point of the Sweet 16 is a Equipment Selection and Maintenance (see below).
Equipment selection and maintenance covers a lot of different things. You have to make sure the equipment is meant to be used for what you are using it for. For personal gear, like a helmet when biking or skiing or a PFD when boating, the equipment must fit properly. And for gear like camp stoves, you much check it regularly to verify that it is still in working order.
From the Sweet 16 of BSA Safety on the Scouting.org website:
5. EQUIPMENT SELECTION AND MAINTENANCE
Most activity requires some specialized equipment. The equipment should be selected to suit the participant and the activity and to include appropriate safety and program features. The supervisor should also check equipment to determine that it is in good condition for the activity and is properly maintained while in use.
