The scope of deadly hazards such as texting and drug use by drivers may be underestimated and not adequately addressed because police aren’t collecting enough information at crash scenes, according to a new report.
A pilot’s decision to continue flying under visual flight rules in weather conditions warranting instrument flight rules, coupled with a company’s culture and lack of a formal safety program, caused a 2015, Ketchikan, Alaska, plane crash, according to a determination made Tuesday by the National Transportation Safety Board (NTSB).
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.
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.
General hazards of welding include impact, penetration, harmful dust, smoke, fumes, heat and light radiation. Welding “smoke” is a mixture of very fine particles (fumes) and gases. Many of the substances in the smoke can be extremely toxic.
Sparks and spatter fly off from the welding arc. Hot metal and sparks blow out from the cutting flame. The workpiece and equipment get hot. The flying sparks and hot metal, slag, spatter, hot workpiece, and hot equipment can cause burns.
The August 28, 2016, nitrous oxide explosion at the Airgas manufacturing facility in Cantonment, Florida was caused by effective process safety management system (PSM), according to the U.S. Chemical Safety Board’s (CSB) final report on the incident, which killed the only Airgas employee working at the facility that day and heavily damaged the plant. The problem: a majority of PSM’s specialized rules are not required for nitrous oxide facilities.
