GAS LOCKOUT/TAGOUT
The Gas Lockout/Tagout procedure is used to protect personnel working on a gas appliance.
Before performing any maintenance or service that requires gas disconnections, follow these
steps:
WARNING: All gas joints disturbed during servicing must be checked for leaks. Do not
use an open flame. Use a hazardous gas tester or a soap and water solution (Bubbles
indicate a gas leak). Failure to comply can cause property damage, injury or death.
WARNING: Do not operate a gas-fueled appliance if a gas leak is present.
1. Locate the gas valve or inlet.
2. Place the valve in the OFF position.
3. Place a tag on the valve indicating that service is being performed on the equipment and
that the gas must remain off until service is complete.
4. Place a locking device on the gas valve or inlet, preventing connection until the lock is
removed.
5. On the appliance, make sure all flame sources are extinguished and/or removed.
6. Bleed residual gas from the unit inlet line and allow time for the gas to dissipate before
beginning service on the appliance.
UNITS MOUNTED ON CASTERS
WARNING: Units mounted on casters must use a flexible connector (not supplied by
manufacturer) that complies with the Standard for Connectors for Movable Gas
Appliances, ANSI Z21.69, CSA 6.16 and a quick-disconnect device that complies with the
Standard for Quick-Disconnect Devices for Use with Gas Fuel, ANSI-Z21.41, CSA 6.9.
WARNING: If disconnection of the restraint is necessary, turn off the gas supply before
disconnection. Reconnect restraint prior to turning the gas supply on and returning the
unit to its operating location.
NOTE: The unit must be releveled front to back and side to side if it is moved for any reason.
