Yellow Alert

THIS YELLOW ALERT IDENTIFIES A POTENTIALLY SERIOUS HEALTH HAZARD

15 NOV 96

Sampling results from burning and carbon arcing operations on painted surfaces have indicated the potential for personnel exposure to arsenic and cadmium above the action level (AL), and in some cases above the permissible exposure limit (PEL). These results, however, are preliminary and Code 106 is continuing to sample burning operations to determine if exposure is occurring. Workers exposed were protected by PPE and have been notified of the sample results.

The AL is the exposure level which triggers awareness training and medical monitoring. The PEL is the amount of a contaminant a worker may be exposed to for 8 hours per day, 40 hours per week for 40 years without adverse health effects.

Unprotected exposure above the PEL to arsenic can cause skin, lung, or Iymphatic system cancer, and can be a skin irritant.

Unprotected exposure to cadmium above the PEL may cause kidney damage and an increased risk of lung and prostate cancer.

Burning on any painted surfaces shall continue to be controlled as LEAD WORK, as the personal protective equipment requirements are similar. It is important that unprotected and unqualified workers do not cross lead work barriers to prevent accidental exposure to lead, and possible exposure to cadmium and arsenic.

Further information is available from your supervisor, Code 106.22 at 6-7896, or in IPI 0077-904A Lead Work Practice - Requirements.

Do not start a job until you are sure of the required control. Remember: Stopping is good progress if an unsafe condition exists.
