Hazards-related incident defined

Risk is defined as a measure of the probability of a hazards-related incident occurring and the severity of harm or damage that conld resnlt. 

A safety professional who gives advice on avoiding, eliminating, or controlling hazards in any of the three elements in the practice of safety (preoperational, operational, and post-incident) must understand how hazards-related incidents occur to be effective. It is basic in problem solving to define and understand the problem, to analyze the cause-and-effect relationships of the subsets of the problem, to consider alternate solutions, to choose and apply the solutions, and to subsequently evaluate their efficacy. 

Severity is defined as the worst credible consequence should a hazard-related incident occur. 

Hazard probability is defined as the aggregate of the likelihood that the potentials of hazards will be realized and that a hazards-related incident will occur. Hazard probability is to be described in probable occurrences per unit of time, events, population, items, or activity. 

Hazard severity is defined as the aggregate of the worst credible outcomes of a hazards-related incident, considering the exposure. 

I suggest that safety professionals give task analysis a greater emphasis as a qualitative predictor of the probability of hazards-related incidents occurring. Task analyses are to define hazardous or inefficient work procedures. 

Risk is defined as an estimate of the probability of a hazards-related incident or exposure occurring and the severity of harm or damage that could result. [ZIO defines risk as an estimate of the combination of the likelihood of an occurrence of a hazardous event or exposure(s), and the severity of injury or illness that may be caused by the event or exposures.]... 

Severity is defined as the extent of harm or damage that could result from a hazards-related incident or exposures. 

Define the Risk. Conclude with a statement that addresses the probability of a hazards-related incident or exposure occurring, the expected severity of adverse results, and a risk category (e.g., high, serious, moderate, or low). Using a risk assessment matrix for that purpose assists one in communicating on the risk level. 

Severity is defined as an estimate of the magnitude of harm or damage that could reasonably result from a hazard-related incident or exposure. (Severity considerations include injury and illness to people, damage to property and the environment, business down time, loss of business, etc.)... 

A concept that is internationally used for risk management decision-making is defined as low as reasonably practicable risk . Once the risk of the operation or item in question has been assessed, a determination must be made of how effective any controls are that are put in place. Acceptable risk is defined as that risk for which the probabiUty of a hazard-related incident or exposure occurring and severity of harm or damage that may result are as low as... 

The Center for Chemical Process Safety (CCPS) defines PSM as "The application of management systems to the identification, understanding, and control of process hazards to prevent process-related injuries and incidents."... 

Since compressed gases and cryogenic liquids are defined as hazardous materials by DOT and TC regulations, the transportation of these products by the gas manufacturers and suppliers is subject to considerable safety-related regulations. Unfortunately many of the more serious incidents leading to injury or fatality have occurred from transporting containers in unsuitable vehicles and in a hazardous manner. 

The concept of risk should be clearly defined and should be included as a major element in the job hazard analysis (JHA) process. Using only loss-related data that is solely based on injuries, incident rates and/or damage does not provide a fioll understanding of the potential for loss-producing events.
