Risk Mitigation

After identifying hazards and ranking risk, a risk reduction plan is used to reduce or eliminate higher risk activities. It is important that hydrogen systems are planned, designed, constructed, and used in a manner that all risks are eliminated or reduced to an acceptable level. In the process of risk mitigation, prevention measures are determined for higher risk activities. For hazards identified as higher than acceptable risk, prevention measures are used to:

  • reduce or eliminate the likelihood of occurrence and/or
  • reduce or eliminate the severity of consequences,

thereby reducing or eliminating the risk.

To eliminate or reduce risk associated with a hazard, the following hierarchy of hazard control is suggested:

  • Eliminate the hazard if you can by modifying the work
  • Substitute for equipment or materials that serve the function adequately but are less hazardous
  • Establish engineering controls which provide reliable, physical isolation from the hazard
  • Establish administrative controls which are rules, procedures, or indicators such as signs that define safe actions for workers or others who might be impacted by the work
  • Provide personal protective equipment
