Things To Consider

Cross-Reference Alternatives

Some MSA MPNs cross individual references to the equivalent Allegro Safety and Bullard model numbers. So, if you're looking for a competitor item that is either out of stock or obsolete, chances are Raptor Supplies has the equivalent MSA products available.


These MSA products range from small to large sizes. They may require careful packaging as some items might get damaged while shipping. Hence, these MSA items are delivered by courier shipment and air freight for minimum downtime.

Frequently Asked Questions

How often should MSA safety products be inspected and maintained?

MSA safety products should be inspected and maintained regularly to ensure they are in good working condition. The frequency of inspections and maintenance varies depending on the product type and usage. It is recommended that users follow the manufacturer's guidelines for inspection and maintenance.

What is an SCBA and why do I need one?

An SCBA (Self-Contained Breathing Apparatus) is a device used by firefighters, rescue workers and other professionals to provide breathable air in hazardous environments. It consists of a mask, regulator and air cylinder to breathe clean air in toxic or oxygen-deficient atmospheres.

What is the difference between an air-purifying respirator and a supplied-air respirator?

An air-purifying respirator (APR) filters the breathable air and removes harmful contaminants from the ambient air. A supplied-air respirator (SAR) delivers clean air from a remote source (air compressor or air tank) to the user's mask. SARs are used in air-contaminated environments for APRs to be effective.
