What is inherent safety principles?
Inherent safety is a proactive approach to process safety in which hazards are eliminated or lessened so as to reduce risk without engineered (add-on) or procedural intervention. Four basic principles are available to attain an inherently safer design—minimization, substitution, moderation and simplification.
What is chemical process safety?
Chemical process safety focuses on preventing incidents and accidents during large scale manufacturing of chemicals and pharmaceuticals – in particular, the unintentional release of potentially dangerous materials and energy to the environment during a chemical reaction, or because of a runaway reaction.
Where is ALARP used?
ALARP is the term used by risk specialists, and duty-holders are more likely to know it. We use ALARP in this guidance. In HSE’s view, the two terms are interchangeable except if you are drafting formal legal documents when you must use the correct legal phrase.
What is the HSE five point plan?
identify what could cause injury or illness in your business (hazards) decide how likely it is that someone could be harmed and how seriously (the risk) take action to eliminate the hazard, or if this isn’t possible, control the risk.
What is the focus of process safety?
Process safety focuses on preventing fires, explosions and accidental chemical releases in chemical process facilities or other facilities dealing with hazardous materials such as refineries, and oil and gas (onshore and offshore) production installations.

What are the concepts of inherently safer processes?
The early versions focused primarily on general concepts, but as acceptance of ISPs by the professional community has grown, the later versions extended the scope to provide more specific guidance on application of those concepts to process design. Today there are a number of working definitions of ISPs, some of which are presented in Box 4.1.
Which is the best book on inherently safer chemical processes?
The Center for Chemical Process Safety (CCPS) aggregated this information in the book Inherently Safer Chemical Processes: (Bollinger et al., 1996; CCPS, 2008b).
Why is intensification and substitution produce inherently safer design?
“Intensification, substitution, attenuation, and limitation of effects produce inherently safer design because they avoid hazards instead of controlling them by adding protective equipment. The term inherently safer implies that the process is safer because of its very nature and not because equipment has been added to make it safer.
