NFPA 77 Recommended Practice on Static Electricity
NFPA 77 静电推荐做法
1.1 Scope.
1.1.1 This recommended practice applies to the identification, assessment, and control of static electricity for purposes of preventing fires and explosions.
1.1.2* This recommended practice does not apply directly to shock hazards from static electricity. However, application of the principles set forth in this recommended practice can reduce such shock hazards to personnel.
1.1.3* This recommended practice does not apply to the prevention and control of static electricity in hospital operating rooms or in areas where flammable anesthetics are administered or handled.
1.1.4* This recommended practice does not apply to lightning.
1.1.5* This recommended practice does not apply to stray electrical currents or to induced currents from radio frequency (RF) energy.
1.1.6* This recommended practice does not apply to fueling of motor vehicles, marine craft, or aircraft.
1.1.7* This recommended practice does not apply to cleanrooms.
1.1.8 This recommended practice does not apply to control of static electricity and static electricity hazards involved with electronic components, which have their own requirements.
Prevent fires and explosions with proper identification and control of static electricity using NFPA 77.
In addition to being a danger to individuals and an operating problem in industry, static electricity is often the ignition source for an ignitable mixture. Guard against fires and explosions using the latest best practices outlined in NFPA 77. You'll access clear guidelines for the assessment of ignition potential and protocols for fire prevention.
Use NFPA 77 to mitigate risks. This document covers
· Hazards of static electricity
· How to control ignition hazards
· Flammable and combustible liquids
· Dusts and fibers
· Gases
· Industrial and commercial processes
· Detection and measurement of static electricity
Important updates in the 2007 edition
· Recognition of positive ground indicators or self-testing ground clamps where indicated by environmental conditions
· Revised guidance on static neutralizers that use a high-voltage power supply
