Yes No Welders, assistants and observers have been supplied with and instructed to wear appropriate eye, face, hearing and hand protection. Yes No Welders and other persons in the work area will wear clothing that protects all parts of the body from burns and damage associated with the ultraviolet radiation produced. Yes No If welding is performed overhead welders will wear leather caps or helmets and shoulder covers. Yes No Welders will wear boots or similar substantial foot gear that completely covers the feet and ankles with pants-cuffs worn on the outside. Yes No If work will be done on an elevated surface an effective means of fall protection is provided. Yes No If work must be performed under wet/damp conditions, mats, platforms or other means are provided that effectively insulate workers from shock hazards. Yes No Workers have been provided and have reviewed appropriate Material Data Safety Sheets for all potentially hazardous materials that will be used. Yes No If compressed gas cylinders are present, they are secured in an upright position and caps are in place when not in use. Yes No Mechanical ventilation is provided to pull welding fumes away from the welder and discharge exhaust fumes safely for welding that must be performed in an area where natural ventilation is not sufficient to maintain a safe atmosphere. Yes No If hotwork will be performed in a confined space, continuous air monitoring will be performed and documented as required by the university(s confined space standard. Yes No If hotwork will be performed in a confined space, compressed gas cylinders will remain outside the space and torches will be removed from space when not in use. Yes No Appropriate respirators are provided and will be used if natural or mechanical ventilation is not sufficient for maintaining a safe atmosphere. (NOTE: Welding or cutting operations that involve materials containing fluorine compounds, stainless steel, zinc, lead, beryllium, cadmium, and mercury are especially hazardous and may require the use of both local ventilation and respiratory equipment to ensure adequate protection) Yes No Gas welding hoses are equipped with flashback arrestors. Yes No Noncombustible or flameproof flash screens are placed as needed to protect other personnel from flash and sparks. Yes No Screens are positioned approximately 2 feet above the floor to allow for maximum ventilation (unless work must be performed at so low a level that they must be extended to the floor to provide protection). Yes No The person(s) who will be performing hotwork are adequately trained and qualified. Yes No Sprinklers located in the area where the hotwork will be performed are operational. Yes No If smoke detectors are present and must be covered/de-activated to prevent false alarms, Environmental Health & Safety has been notified. Yes No Cutting and welding equipment is in good repair. Yes No Ducts and conveyor systems (that might carry sparks to distant combustibles) are suitably protected or shut-down. Yes No Floors have been swept and cleared of all combustibles within 35 feet of hotwork (if possible). Yes No Combustible floor or wall surfaces within 35 feet of hotwork are wet down or protected with damp sand, metal or other safety shields. Yes No There are no unprotected combustible materials or flammable liquids in the hotwork area. Yes No All combustibles that are likely to be ignited by conduction or radiation are moved away from the opposite side of partitions, walls, ceilings or roofs. Yes No All wall and floor openings are covered. Yes No Covers that need to be suspended beneath the work to collect sparks are installed. Yes No All combustibles are cleaned and removed from equipment near the hotwork area. Yes No Containers on which hotwork will be performed are purged of all flammable vapors. Yes No Provisions have been made to provide a fire-watch during hotwork operations and for at least 30 minutes after the work is completed. Yes No The fire watch is supplied with suitable fire extinguisher and other appropriate fire-suppression materials. Yes No The fire watch is trained in the proper use of suppression equipment and how to sound the alarm if necessary. Yes No Adjoining areas, above and below, have been checked for the necessity of fire watch. Yes No An approved first-aid kit is readily available. Yes No A phone with emergency numbers posted nearby is available and accessible.
