Know Your User and Your Product’s Hazards

You may also want to conduct a risk analysis. The hazard analysis identifies the hazards that could produce injury or damage, and the risk analysis estimates the likelihood that an adverse event would occur. To illustrate the difference, consider a modern walk-behind gasoline-powered lawnmower with a “dead man switch” that stops the blade from turning when the operator’s hand leaves the handle. The hazard is the spinning blade that could amputate fingers if the operator reached into the discharge area to clear a blockage. The risk is the likelihood of that event happening. If the dead man switch has not been disabled, the risk is very low, since it would be nearly impossible to hold the handle (preventing the dead man switch from engaging) and simultaneously reach into the discharge chute. However, the risk might be considerably elevated if the dead man switch were easy to disable and if the operator were motivated to do so (for example, because the switch not only stopped the blade, but also shut off the engine, requiring a restart each time).

The purpose of the hazard analysis is to develop a list of hazards which are of such significance that, if not controlled effectively, there is a reasonable likelihood they will cause illness or injury. Hazards that are not reasonably likely to occur would not require further consideration within a HACCP plan (but these should be kept under review in the event of process changes that require revised analysis). It is important that the hazard analysis is comprehensive: it should consider the ingredients, each step in the process, product storage and distribution, and final preparation and use by the consumer.
Hazard Analysis
Published in Charles D. Reese, Occupational Safety and Health, 2017
Hazard analysis is an organized effort to identify and analyze the significance of hazards associated with a process or activity. Doing a hazard analysis will hopefully identify any unacceptable risk faced when in the workplace and determine the options for managing or eliminating those risks. This is why hazard analysis can shine a light on facility or design problems, and unsafe operations that cause property damage, injuries, and even death. Also, once the problems are identified, the company can identify risk management strategies to address them.

Hazards can be understood as a state or condition that can lead to a loss of something of value to stakeholders.23 Hazard analysis is defined as the process of examining a structure, system, or component in order to identify hazards and triggers of hazards with the goal of eliminating, mitigating, or controlling them.24 There exists a considerable amount of research regarding risk assessment techniques, covering a spectrum from traditional static to dynamic analysis.25 In 2000, for example, Glossop et al. discussed 40 different techniques for hazard analysis. They discussed the application of these techniques to various project phases (e.g., project initiation, design, development, operation, decommissioning, etc.).26 None of the methods reviewed by Glossop et al. provides coverage for every phase; thus, their work supports the need for a new or combined approach. Rather than include all available hazard analyses, this review discusses five well-known static analysis methods: failure modes and effects analysis (FMEA), fault tree analysis (FTA), hazard and operability analysis (HAZOP), systems theoretic process analysis (STPA), and purpose graph analysis (PGA) (Ref. 27).
Jens Rasmussen’s risk management framework

The purpose for the hazard analysis is to take account of the diverse kinds of hazard sources that require different hazard control strategies in different work systems. Hazards and their physics are identified from the generic AcciMap. The targets of risk can be inferred from the generic AcciMap, while means of hazard control can be strengthened by intervening in the physics of the hazards and by developing an ecological information system for system deciders.
