Tie-Ins to Company Equipment
Written permission from a company representative should first be obtained before contractors are permitted to tie into existing company facilities, including pipelines, electrical power circuits, and all other equipment.
Extension and Cheater Cords
Power tools and portable electrical test equipment may or may not be rated for use in classified areas. They are equipped with standard non-explosion-proof plug ends, making it sometimes necessary to use an extension cord when plugging into explosion-proof receptacles.
Due to the hazard of arcing electrical equipment or connections when plugging in this equipment, use the following practices:
- Use only electrical equipment that is approved for use in a classified area.
- Make sure a Hot Work Permit has been issued and the atmosphere has been tested to ensure flammable, gas-free conditions.
- Connections should be taped to prevent them from separating.
- Connections made with explosion-proof ends should be made outside of the classified areas.
- The last connection made should always be plugging the cheater cord into the explosion-proof receptacle.
- Break the connection at the explosion proof receptacle first when the job is completed.
- Remove from service and destroy extension cords that are frayed, taped, or otherwise damaged.
- Use extension cords only for temporary situations.
