Toms Outlet Asphyxiation hazards in weldin

Asphyxiation hazards in welding and allied processes

This guidance gives advice on asphyxiant gases used when welding metal fabrications and pipes, and in particular a technique known as purge damming, (containment of purging gasses in the area being worked on). It will be Toms Outlet useful for employers and workers planning this type of work, and for inspectors assessing whether the controls in place are adequate to control the risks to health and safety.

The consequen Toms Outlet ces of exposure to an oxygen deficient atmosphere can be fatal, yet with reasonably practicable controls, as explained below, the risk can be reduced to an acceptable level.

Accident history indicates that multiple workers are often affected. This document describes the processes and associated hazards and gives advice on precautions to ensure the safety of all persons who may be affected.

This document does not deal with:

the fire and explosion properti Toms Outlet es of welding gases;

‘inerting’ fabrications to prevent fire and explosion;

the toxic or harmful properties of welding fumes; or

the effectiveness of weld shielding.

Common uses of asphyxiant gases

The most common use of inert gas in welding is during gas shielded electric arc welding eg MAG, MIG and TIG. The inert gas is delivered directly from the welding torch automatically. It creates a temporary protective atmosphere around the arc and molten weld pool, excluding air and preventing the oxygen in the air adversely reacting with the weld.

Inert gas delivered directly from the welding torch is generally sufficient to create a temporary protective atmosphere, however the inert gas may not pass though the unwelded joint in sufficient quantity to exclude air from the back of a weld joint. Excluding air from the back of a welded joint is particularly important when the corrosion resistance of the welded joint is important or oxidation defects are not acceptable. This is often the case when welding corrosion resistant metals such as stainless steel and ‘kunifer’ (copper/ nickel/ iron alloys) and when removing defects out of the back of a weld joint is undesirable or impractical. In these circumstances inert gas may be used to purge air from the back of the joint during welding operations.

Types of gas and their properties

For smaller jobs the welder may purge air from behind the weld using the same gas supply as for the welding gun. This may be a proprietary mix such as argon/ helium or argon/ helium/ CO2. Mixed gases tend to be significantly more expensive than pure argon, as a result larger scale purging operations tend to use argon.

Although metal active gas (MAG) welding does not use a true inert gas (often carbon dioxide or a mixture of gases) th Toms Outlet e gases used do not contain sufficient oxygen to sustain life. Similarly nitrogen is not a true inert gas as it can chemically react with metal at welding temperatures. However it is cheap so may be used to purge air, particularly if large quantities of gas are needed to purge a large void.

The city medical examiner’s office said an autopsy was inconclusive, and more tests were needed.Little was immediately clear about the circumstances of Rodriguez’ pregnancy and the baby’s death. Some neighbors told reporters they hadn’t realized she was carrying a child.Rodriguez remained hospitalized Friday after the find a day earlier, and a woman who answered the phone at a possible home number for her said she knew nothing about the matter. A message left at another possible number for Rodriguez wasn’t immediately returned.A securit Toms Outlet y guard found the child’s body in a bag Rodriguez was carrying Thursday as she and another 17 year old girl, Francis Estevez, browsed at a Victoria’s Secret store in midtown Manhattan, police said. The guard stopped them on suspicion they were shoplifting, and both were ultimately arrested on petit larceny Toms Outlet charges.Rodriguez could face more serious charges related to the baby’s death.The Associated Press is id Toms Outlet entifying both teens because in New York, older teens are treated as adults, and their cases are handled in criminal courts. Suspects between 7 and 15 may be charged as juveniles and their cases handled in family courts.A woman who said she was Estevez’s mother hung up after saying she hadn’t spoken with her daughter since her arrest. It wasn’t clear whether either Estevez or Rodriguez had a lawyer.

Toms Outlet Asphaltage de la rue Tremblay

Asphaltage de la rue Tremblay

(Saint Henri de Taillon) La municipalit de Saint Henri de Taillon ne pliera pas devant les riverains qui rclament l’asphaltage de la rue Tremblay, un lien routier qui dessert une vingtaine de rsidences.

La semaine dernire, Toms Outlet un groupe de citoyens a bloqu l’accs leur secteur afin de protester contre l’organisation municipale de la localit jeannoise. On souhaitait ainsi faire entendre un mcontentement qui ne cesse de s’amplifier depuis des annes.

L’asphaltage du tronon, qui s’tire Toms Outlet sur un ki Toms Outlet lomtre, ncessiterait un investisse Toms Outlet ment d’environ 500 000 dollars. Le maire Andr Paradis a t catgorique sur ce point : Nous n’avons pas les moyens.

Lundi soir, lors de l’assemble publique du conseil, le maire a ritr sa position, avant de devoir interrompre la sance d’un coup de marteau.

Ils ont pos leurs questions, ont exprim leurs dolances, et nous comprenons ce qu’ils disent. Mais nous vivons dans un milieu rural et nous n’avons pas la capacit de rpondre leur demande, a t il racont, au terme de l’assemble.

Selon Andr Paradis, il n’existe aucun programme d’infrastructure destin aux villgiateurs.

Nous servons encore une fois de punching bag entre les citoyens et le gouvernement. Tout est fait pour les milieux urbains. Que pouvons nous faire de plus comme conseil ?
