Hazardous Environment Regulations

What is a Hazardous Location?

Hazardous environments usually contain amounts of explosive gasses or dust either during normal or abnormal operation.
The National Fire Protection Association (NFPA) has several documents that discuss hazardous environment locations and protection methods. NFPA 70 (National Electric Code) contains detailed classification of hazardous areas and electrical requirements for equipment used in those areas. The International Electrochemical Commission (IEC) is an international committee that has similar classifications as identified in the table below.

There is a very dangerous misunderstanding that "EE" rated aerial work platform machines are safe for use in hazardous locations. These "EE" machines have minimal spark protection and do not comply with the strict electrical requirements of NFPA 70 (NEC) for hazardous environments.

Man & Material Lift Engineering designs and builds three types of aerial work platforms as well as personnel vehicles for use in hazardous location.

These man lift machines are designed for typical applications at locations such as:

• Paint Booths (Class I, Division I, Group D, Zone 0, Group IIA)
• Grain Processing Plants (Class II, Division I, Group G)
• Plastic Media Blasting Booths (Class II, Division I, Group F)
• Petro-Chemical Plants
• Underground Tunnels
• Aerosol Plants
