OIL & GAS WELL DRILLING RISKS - WELL SITE IGNITION SOURCES

There are a number of potential sources of ignition for flammable gases and liquids on the drill site. It is necessary to provide for a general ignition safety program which could pre-empt potential hazards of fire and explosion.

Potential Hazard:

Ignition and explosions of flammable gases or vapors from:

Internal-combustion engine sparks

Open flames from any source

Smoking

Welding operations

Electric power tools

Two-way radios

Vehicles with catalytic converters

Portable generators

Possible Solutions:

Provide spark arrestors for internal-combustion engines.

Post "NO SMOKING" signs wherever a flammable gas or vapor hazard exists.

Locate "spark producing" equipment or facilities well away from potential hazard areas.

Prohibit vehicles with catalytic converters from the immediate vicinity of the rig.

Prohibit open flames from the vicinity of the rig.
