Here are the definitions I use, and OSHAâs Hazard: Any facility, location, equipment, tool, job, task, or action that presents a potential of serious injury or death to any employee. This is the OSHA view. Serious injuries are those that result in time loss (beyond the three day grace period) and/or hospitalization beyond an emergency room visit. OSHA: A hazard is the potential for harm. In practical terms, a hazard often is associated with a condition or activity that, if left uncontrolled, can result in an injury or illness. Risk: It is related to Hazard, it is the potential of harm or loss (generally economic) and its impact to the company or individual from a potential hazard.
the derived SI unit of power, equal to 1 joule per second; the power dissipated by a current of 1 ampere flowing across a potential difference of 1 volt. 1 watt is equivalent to 1.341 Ã 10â3 horsepower W.
There are many ways to approach 1 unit of Joule. It is equal to energy transferred to an object when 1N of work is done for object to move 1m. It is also equal to work required to move 1C charge in 1V field. It is equal to energy required to produce 1W energy in 1s. Enery equal to 1A current flowing through 1(ohm) resistance for 1s.
