Safe Distance For Welding Flash

This Code applies to all workplaces covered by the WHS Act where welding processes are carried out and to all persons involved in these activities. B The distances are based upon the worst-case exposure conditions.

Welding Garage Safety Guide From Setup To Ppe To Proper Welds

The Rayleigh scatter of the atmosphere will probably be a significant factor in reducing the ultraviolet intensity in the image in your eye at this distance.

Safe distance for welding flash. By Lawrence Date 10-23-2001 1347. Knowledge and precautions can prevent fires and violent explosions. Undertaking on how to manage health and safety risks associated with welding.

The equipment used today is safe but every year hundreds of employees are injured or die as a result of improper use. Consider if you could avoid or reduce exposure by doing the job in a different way. C Invisible actinic UVR poses a potential hazard to cornea called welders flash and skin much like sunburn and exposure is cumulative with each exposure over an 8-h workday per 24-h period.

You and the fire watcher should wait for at least one half hour after all welding is finished to find and put out any smoldering fires that may have resulted from your welding. Proper storage of each cylinder is essential for safetybut because cylinders need to be stored away from heat and sunlight a welding booth usually isnt a good storage location. Therefore if you are a short distance from an arc even a very short exposure to the arc flash can result in injury.

12123 Protective clothing and equipment. Although this Code focuses on welding processes it may also be relevant to manage the risks associated with allied processes. F and where the altitude does not exceed 3300 feet 10058 m and shall be suitable for operation in atmospheres containing gases dust and light rays produced by the welding arc.

Water gauge WG is a measure of negative pressure. Eye damage and minimum safe distances from the welding arc. As a result personnel must be subject to adequate protection if theyre closer than 10 metres from an arc flash.

A worker involved in welding or burning operations must wear a flame resistant work clothing b gauntlet gloves of leather or other suitable material and arm protection. Maximum UVR for exposure angle arc gap and electrode diameter. Freely movable hoods intended to be placed by the welder as near as practicable to the work being welded and provided with a rate of air-flow sufficient to maintain a velocity in the direction of the hood of 100 linear feet 30 m per minute in the zone of welding when the hood is at its most remote distance from the point of welding.

Preventing Welding Flashback Oxy-acetylene torches have been used for many years for cutting welding brazing and heating of metals. By boilermaker On 02-Jul-01 1717. By bhiltz Date 10-22-2001 1810.

For example you must be behind a Welding Curtain or wearing personal eye protection. Many times welders transport cylinders to and from a welding area but in some cases maintenance workers perform this function before and after work hours. You must train workers especially those new to the job.

Standard machines for arc welding service shall be designed and constructed to carry their rated load with rated temperature rises where the temperature of the cooling air does not exceed 40 deg. This reduces the possibility of electric shock from simultaneous contact with any parts of 2 different systems irrespective of the voltage of either one to. There is no clearly defined limit since the distance depends upon the exposure time welding process welding current and other environmental conditions.

These arms generally move between 560 and 860 cubic feet per minute CFM 900 1400 m3hr of air but use low vacuum levels 3 to 5 inches water gauge 750 1250 Pa to minimize power requirements. Your question is a good one and I too would like to see a sourced responce to it. If you are welding within 35 feet or so of flammable materials you should have a fire watcher to see where your sparks are flying and to grab an extinguisher or sound the alarm if needed.

You must protect your workers health by controlling the risks from welding fume. When using 3-phase welding circuits or single-phase circuits derived from different phases of the mains supply segregate the welding positions connected to different phases or transformers by partitions or distance whenever reasonably practicable. 12 m 40 ft is the recommended minimum distance from which an electric welding arc should be seen by the unprotected eye.

Consider using respiratory health surveillance. You probably need to be several km away to be safe where the welders arc is just a pin point as small as a star seen from Earth. The US Army have carried out trials which propose distances of between 3 and 20 metres for an exposure time of 10 minutes for MMA SMA.

Reply A safe distance is 50 feet. One cause of fires and explosions is high.
