Even t - Descrip tion At approximately 1140 hours0.0132 days <br />0.317 hours <br />0.00188 weeks <br />4.3377e-4 months <br /> on. February. 4,1981 a class A fire (Foam Rubber) 2 occurred in L the area above the Yarway rac'r-the 51' level in the reactor.

]

building. - The firn was ignited by wel'du.., wads falling on foam rubber. that i

a contractor'had emplaced to prevent pipes from contacting temporary thermal shielding. installed for the welding operation. - The fire burned for approximately

. two minutes before it was identified and extinguished by-the contractor supplied fire watch using a portable dry chemical extinguisher.

' Contractor personne11 stated that they attempted to notify the control room using the emergency channel on the plant intercom system, however they did not mention a fire and gave up af ter three attempts because the fire was out.

The Fire Protection Engineer was notified when a Boston Edison employee noticed a large cloud of dry chemical hanging in the area, and called the FPPO Office.

Cause

a The cause of this fire was the failure to follow station procedure 1.5.5 re-garding removal of combustible materials.

Corrective Actions

All work'by the contractor involved was immediately stopped, and not allowed to resume until the contractor had demonstrated a thorough understanding of all applicable station procedures regarding fire protection p actices.

j The station cutting / welding procedure (1.5.5) is being revised to require appraval to start work each day from the fire protection engineer or his des-ignated ' alt.ernate, and a temporary procedure change was effected requiring that individuals assigned as fire watches in critical areas be qualified members of the plant fire briFade.

To prov!,de permanent corrective action to prevent occurrences of this type, a fire watch training program is being developed to ensure that individuals as-signed as fire watches receive instructions in fire protection techniques.
