Full face helmet. Don't want to use a breath deflector. Is there a liquid or creme that can be applied to the shield that will keep it from fogging?
if you are the original owner and you registered you alarm they will contact you with any and all applicable recalls
This depends on the type of acid and the volume of the spill. Hopefully you keep the appropriate acid spill kit readily available and have properly trained people designated to respond. At work I frequently deal with hydrochloric acid. When a small spill occurs it is contained with chemical absorbent damns and immediately treated with baking soda which is kept nearby. For large spills (which we have never had but do have a plan in place) we evacuate the area and call an emergency response company to perform cleanup.
