2. Exposure to chemical contamination - through skin contact and ingestion. Ongoing air monitoring during project tasks will provide data to ensure that vapor concentrations are within acceptable ranges and will provide adequate selection criteria for respiratory and dermal protection. A Photo Ionization Detector (PID) shall be utilized for monitoring with a 1 part per million (ppm) detection limit. • If PID readings taken in the breathing zone exceed 100 ppm, a NIOSH approved air-purifying respirator with organic vapor cartridges must be worn by all site workers within any area where monitoring results exceed 100 ppm. • If PID readings taken in the breathing zone exceed 750 ppm, Level B protection will be required. Personnel must leave site immediately and contact FSS or Health & Safety Manager for further instructions. • Respirator cartridges will be changed once per day as a minimum. This can be accomplished at the end of the work day during respirator decontamination. If odor breakthrough is detected while wearing the respirator or breathing becomes difficult, change cartridges immediately. 9.1 Tasks Performed Within a Confined Space • Mechanical injuries and chemical injuries are possible when working in confined spaces. To minimize potential for these injuries, effective lockout/tagout and blocking/blinding procedures must be employed. • Hazardous atmospheres may exist or develop within confined spaces. It is important to identify these atmospheres and to proceed to eliminate the condition and/or protect against it. Monitoring shall include oxygen, LEL and toxic contaminant readings. Regulatory limits for work conditions are: 19.5-23% Oxygen < 10% LEL E < 100ppm Toxic Contaminants Varying conditions will dictate PPE particulars. Monitoring will occur prior to entry and at specified intervals during entry. (Entry into IDLH atmospheres require HLR with egress or SCBA and the use of buddy team procedures.) • Safe work practices and emergency rescue require specific equipment for confined space entries. All entry personnel will wear harnesses, lifelines and lanyards. (Exceptions by written variance from Health and Safety only.) Entry through top manways/openings require the use of an Santochi&Bravante LLC American Savings Bank 20 Corporate Plaza 9620-041-1 Newport Beach,California 16 222 El Dorado
