• Review and sign Attachment 1 to SOP-121, Respiratory Protection, Information for
Voluntary Use of Respirators (Attachment 5);
• Review the proper use (including using the nose clip), limitations, care and the information
provided with the respirator;
• Verify the respirator is a NIOSH-approved respirator for emergency escape.
• Verify the respirator is for chlorine gas;
• Verify the respirator is in working order, that the end of service life has not expired (some
models have an “End of Service Life” blue dot to indicate if the respirator has not expired);
• Wear goggles, or at least safety glasses with side shields when in areas where chlorine is
stored or used;
• Evacuate the area immediately when the first alarm sounds, or when told to do so by plant
personnel or others if there is no alarm;
• Proceed directly to the nearest designated assembly area for a head count, moving
perpendicular to the wind direction;
• Contact the PM and RHSM if escape respirators are planned to be used.
2.2.4 Compressed Gas Cylinders
• Valve caps must be in place when cylinders are transported, moved, or stored.
• Cylinder valves must be closed when cylinders are not being used and when cylinders are
being moved.
• Cylinders must be secured in an upright position at all times.
• Cylinders must be shielded from welding and cutting operations and positioned to avoid being
struck or knock over; contacting electrical circuits; or exposed to extreme heat sources.
• Cylinders must be secured on a cradle, basket, or pallet when hoisted; they may not be hoisted
by choker slings.
2.2.5 Concrete and Masonry Construction
(Reference CH2M HILL SOP HSE&Q-302, Concrete and Masonry)
• Wear appropriate personal protective equipment (eye/face protection, gloves, rubber boots)
when in areas where concrete is being poured.
• Protruding reinforcing steel (rebar), onto which personnel could fall, must be guarded to
eliminate the hazard of impalement.
• Stay as clear as possible of all hoisting operations. Loads, including concrete buckets, shall not
be hoisted overhead of personnel.
• Maintain a safe distance from formwork and shoring being removed from concrete structures.
• Maintain a safe distance from precast and lift-slab concrete being lifted into position until
physically secured.
• Do not stand behind the tensioning jacks during post-tensioning.
• Do not ride concrete buckets.
• Do not enter limited access zones during concrete or masonry wall construction.
