This is also the Risk Assessment matrix that all military services and several other government agencies used in program/product development. It is included in Mil-Std-882D, "DOD Standard Practice for System Safety" - released February 2000. "System Safety" is generally the equivalent to "Product Safety". This standard is not a specification standard but a management standard. It provides a list of different tasks that can be imposed on a contractor to investigate for hazards, assign value to the hazard risk, and evaluate corrective action for elimination or mitigation of the risk. It is a good tool.
Another tool that complements this for risk assessment and is well worth the cost is the "System Safety Analysis Handbook - A Source Book for Safety Practictioners" published by the System Safety Society. You can get a copy of MIL-STD-882D at the following site: http://www.system-safety.org/ They also have a copy of MIL-STD-1472F - "DOD Design Criteria Standard Human Engineering" - released August 1999 You can also purchase either a paper copy or CD of the Handbook from here. The site provides a table of contents and an matrix of the methods and practices included in the handbook. Here is a excerpt from the handbook description: "The Handbook is a stand-alone document. The 2nd Edition of the Handbook has 626 pages and contains a compilation of 101 analysis techniques and methodologies, plus other related information for every safety practitioner. It addresses system safety planning, Process Safety Management (including OSHA and EPA requirements), software system safety, and a section on the application of fuzzy and hybrid mathematics to safety analysis. A glossary is included. The reference section includes a recommended readings list." rloop%[email protected] on 12/08/2000 10:34:51 AM Please respond to rloop%[email protected] To: jorgensen%[email protected] cc: emc-pstc%[email protected] (bcc: Oscar Overton/Lex/Lexmark) Subject: RE: Risk assessment Hi Stig, One of my side jobs is in the Army National Guard Field Artillery. We perform a risk assessment at each firing point we pull into using an Army manual, FM 100-14 (Risk Management). I was surprised to see how closely their documentation parallels EN 1050 in many aspects. Here's a quick look at some of the terms and definitions used that relate to your inquiry: Hazard Severity: * Severity - The expected consequences of an event in terms of degree of injury, property damage or mission-impairing factors. * Catastrophic - Death or permanent total disability, system loss, major damage, significant property damage or mission failure. * Critical - Permanent partial disability, temporary total disability in excess of three months, major system damage, significant property damage or significant mission degradation. * Marginal - Minor injury, lost workday incident, minor system damage, minor property damage, or some mission degradation. * Negligible - First aid or minor medical treatment, minor system impairment, little or no impact on mission. Hazard Probability: * Probability - The likelihood an event will occur. * Frequent - Occurs often or continuously experienced. * Likely - Occurs several times. * Occasional - Occurs sporadically. * Seldom - Unlikely, but could occur at some time. * Unlikely - Can assume it will not occur Hope this is helpful.
