The answer is yes in almost all cases. It make sense to save on energy costs by returning heated or air conditioned air back into the workspace after it exits the dust collector. When using recirculating dust collection systems, special safety and performance concerns must be addressed. Often, a… Continue

Introduction:- Nearly everyone has heard a practical joker say “This one is gonna kill ya”. Well, hopefully it never will. However, practically jokes invite danger. The building trades industry is potentially dangerous and anything that unnecessarily increases the chance of an injury must be eliminated. Horseplay benefits no one and usually only builds up resentment and fosters relation. Practical jokes should be discouraged. At some point, if they continue they need to be… Continue

Flashback arrestors on oxy-fuel welding rigs are most commonly located at the regulator. However, torch makers like Victor place them in the torches. Do any list members know if US OSHA has ever specified in writing where they must be located? Many say that placing them both at the regulator and torch is not good because it restricts gas flow too much.

Ps. Here in Tuxpan, Mexico we are just using them in the torch heads.

Last week I asked if you were a safety warrior. My question was about your attitude and approach to safety and how you act in regards to safety in the workplace.
We hear a lot about the importance of diversity in the workplace, but it is more about diversity of ideas and actions than anything else. If we were all warriors, fighting the good fight against all things that compromise employee safety, we would eventually be exhausted. It's a fight that can't be won by warriors alone.

Fire hazards are some times overlooked on the jobsite because they are a common part of every work day. We regularly use fuels, cleaners, solvents, adhesives, etc. that are flammable and these products alone are usually safe but when combined with carelessness and lack of taking the proper safety precautions, they can become volatile and very dangerous.
In order to start a fire you need three ingredients: FUEL ( such as wood, paper, gasoline etc.); OXYGEN; and a source of IGNITION (such as… Continue

Work activity or the presence of harmful substances in construction environments frequently produces airborne contaminants. These contaminants can be controlled by isolating them from the breathing zone or by providing adequate ventilation. Ventilation is one of the most common engineering control methods and can be defined as the movement of fresh air into a space in order to replace contaminated air and/or control the temperature in a space.
Natural ventilation usually does not provide a… Continue

Experience teaches us a lot about working around cranes but often the lessons are costly. we’ll discuss things we should and should not do when working around this equipment.
It’s smart move on your part to stay out from under suspended hooks and loads. There’s always a chance that during a lift, the load could shift and fall. It may be a slim chance because of the good rigging techniques we use but once is all it takes to cause a serious injury or a fatality. Also stay clear of swinging… Continue
