How many breathing apparatus masks are needed for 1,001-2,000 lbs. of refrigerant?

For a quantity of refrigerant between 1,001 and 2,000 lbs., two breathing apparatus masks are required. This requirement is based on safety regulations that dictate the necessary personal protective equipment (PPE) needed when handling large amounts of refrigerants, which can be hazardous in the event of a leak or release.

Refrigerants can displace oxygen in the air or be toxic, necessitating the use of appropriate respiratory protection. The determination of this number is calculated to ensure that adequate safety measures are in place to protect workers from potential exposure, as one mask may not suffice. Therefore, the regulation ensures that personnel have the equipment necessary for two individuals, thus enhancing safety protocols during operations involving significant quantities of refrigerant.
