In the workplace, irritant contact dermatitis can develop after a short, heavy exposure or a repeated or prolonged, low exposure to a substance. The appearance of irritant contact dermatitis varies considerably according to the conditions of exposure. For example, an accidental contact with a strong irritant causes immediate blisters. Contact with a mild irritant may only produce redness of the skin. However, if the irritation continues, small lesions or sores appear on the reddened area; afterwards crusts and scales form. The skin damage usually heals a few weeks after exposure ends if no complications have arisen (e.g., no infections occurred).
Dermatitis is a localized inflammation of the skin. In general, inflammation refers to a condition in the body when it is trying to react to a localized injury of tissues. Signs of inflammation include some or all of the following: redness, heat, swelling, pain.
OSHA has issued a final rule that updates regulation established 40 years ago to prevent chronic beryllium disease and lung cancer in American workers by limiting their exposure to beryllium and beryllium compounds.
Three of the nation’s leaders in occupational health and safety have launched a new online course intended to help employers integrate their health and safety programming in ways that can bolster bottom-line results while improving the health and wellbeing of their workers.
A revision of ANSI R15.06-1999, this standard provides guidelines for the manufacture and integration of Industrial Robots and Robot Systems with emphasis on their safe use, the importance of risk assessment and establishing personnel safety.
1. Read the Book. A welder’s operating manual contains important safety information, as well as information procedures that maximize the machine’s potential. Make sure everyone who operates the machine is familiar with its contents.
1 Electric shock
Electric shock is one of the most serious and immediate risks facing a welder. Electric shock can lead to severe injury or death, either from the shock itself or from a fall caused by the reaction to a shock.
Electric shock occurs when welders touch two metal objects that have a voltage between them, thereby inserting themselves into the electrical circuit.
Q. What is a fume plume?
A. A fume plume is the clearly visible column of fume that rises directly from the spot of welding or cutting. Welders and cutters should take precautions to avoid breathing this area directly. Ventilation can direct the plume away from the face.
Before any welding is conducted outside of a designated welding area, a responsible individual must inspect the area and identify precautions to be taken preferably on a written Hot Works permit. Fire extinguishers must be ready for immediate use. A fire watch lasting at least 30 minutes after the welding or cutting operations is required if more than a minor fire might develop.
