Explosion Mitigation
       Venting - Containment - Suppression

OSHA recommends that NFPA standards be consulted for the design requirements associated  with the explosion protection of process equipment.

The referenced standards include significant new responsibilities for the owners of enclosures requiring explosion protection.

Chapter 11 of NFPA 68 has sections on required documentation, installation and inspection.  Specifically, Section 11.2 details information an owner must keep up-to-date and on file for each vented enclosure.        See List

MAC Equipment wants to help you meet your obligations under these new requirements.

The US Chemical Safety Board (CSB) is an independent federal agency charged with investigating industrial chemical accidents.  The CSB has provided the following video which illustrates how dust from industrial processes can become the fuel for devastating explosions.

The regulations put forth by OSHA and the NFPA regarding the handling of combustible dusts are intended to protect your employees and facilities from explosions fueled by combustible dust. 

There are three primary methods of explosion protection:  venting, containment and suppression.  Each of these methods of explosion protection offer varying degrees of cost and flexibility depending on the enclosure and its location. 

Trained MAC experts can assist you in understanding the explosion protection methods available and aid you in selecting the right one based on your unique needs.
