Temporary control measures such as providing temporary ventilation or achieving a satisfactory pre-entry gas test will not cause a confined space to be. What is a confined space? · the presence or reasonable foreseeable presence of: flammable or explosive atmospheres - harmful gas, fume or vapour - free flowing. monitor any potential toxic gases or substances within the confined space, and monitor oxygen levels, to make sure all values stay within safe parameters. Mar 15,  · A Permit-Required Confined Space is confined space that has one or more of the following characteristics: Contains or has the potential to contain a hazardous atmosphere; Contains a material that has the potential for engulfing an entrant; Has an internal configuration such that an entrant could become trapped or asphyxiated; or. confined space plan for work in permit and non-permit required confined spaces on University of Louisiana at Lafayette property. • Gases or vapors which can displace oxygen • A potential for low or high levels of oxygen, % and below or % and above. Nov 26,  · Confined space risk assessments are systematic processes that ensure proper safety and evacuation procedures are followed and necessary permits acquired when working in confined spaces. Confined space risk assessment templates and safety checklist are used to check and record atmosphere testing, adequate ventilation, PPE usage, staff signatures. Confined Space Last Contained Other Toxic Gas (specify) Atmospheric testing is required for any changes in the confined space or surrounding work. Permit Required · Oxygen below % or above % · Presence of toxic gases (carbon monoxide & hydrogen sulfide are most common) · Presence of combustible gases. Hazards in Confined Spaces · Suffocation (due to oxygen deficiency) · Fire and explosion (by flammable gases and vapours) · Poisoning (by toxic gases, vapours or. Working in confined space is dangerous — no air circulation and lack of oxygen, accumulation of toxic and flammable gases and small entry ways.

Fire/Explosion Hazards — By Flammable Gases and Vapours Gas Testing and Monitoring of the Confined Space Atmosphere. “atmosphere” () refers to the gases, vapours, dusts, fumes or mists within a confined space. “hazard” .) is something with the potential to cause harm (this. An example is the interior of a storage tank, occasionally entered by maintenance workers but not intended for human occupancy. Hazards in a confined space.

There is a great danger that flammable gas and vapour may collect in a confined space, and these may ignite when welding or cutting takes place leading to an. Hazard Knowledge · Purging confined spaces with an inert gas to remove flammable or toxic gases, vapours or aerosols · Naturally occurring biological or chemical. Flammable gas, vapor, or mist in excess of 10% of its lower flammable limit (LFL/LEL). Sources of flammable gases may come from leaking acetylene hoses, methane.
