Protective equipment risk assessment

Exposure. With the establishment of cumulative risk assessment requirements of the FQPA, there is much more of a need to focus on exposure. Prior to FQPA registrants could often live with the worst case result of an individual exposure assessment. Hazards could be mitigated with additional testing and/or label recommendations for additional personal protective equipment. Cumulative assessment and a certain total allowable risk shows that worst-case exposure analyses soon cause the risk cup to overflow. Prudent long-term strategy for a... 

The exposure value thus yielded provides a measure of the skin exposure with and without consideration of a protective garment and gloves (personal protective equipment = PPE), and may be taken directly for comparison with appropriate data from relevant toxicity studies for assessment of the risk via the dermal route. 

Offshore facilities are dramatically different from onshore facilities because instead of being spread out the equipment is segregated essentially into compartments or separated into a complex of platforms. Offshore facilities pose critical questions of personnel evacuation and the possibility of total asset destruction if prudent risk assessments are not performed. A through analysis of both life safety and asset protection measures must be undertaken. These analyses should be commensurate with the level of risk a particular facility represents, either in personnel exposed or financial loss. An unmanned wellhead platform might only require the review of wellhead shut-in, flowline protection and platform ship collisions to be effective, while manned drilling and production platforms may require the most extensive analysis. 

All methods should be carried out only by competent persons and with adequate supervision when necessary. All obligations under The Control of Substances Hazardous to Health Regulations 1999 (COSHH), should be observed, and risk-assessment documentation completed. Appropriate personal protective equipment should be provided and worn whenever recommended. Persons carrying out the procedures in this manual do so entirely at their own risk, and neither the author, publishers, or anyone mentioned in, or connected with this publication can be held in any way responsible for any accidents no matter how caused. 

Exposure scenarios specify the conditions in which the chemical is to be used (including the protective equipment to be used, working practices, products it is incorporated into, how consumers use those products and how these are disposed), limiting the range of the conditions that must be considered in the exposure assessment. The exposure scenario is annexed to the chemical safety data sheet that is passed to downstream users of the chemical. Those downstream users are required to pass information back to their suppliers about their use of the substance, the exposure to the substance involved in that use and the practicality of specified risk reduction measures. If a use is significantly different from those identified in the CSA, the user must report this to the European Chemicals Agency and prepare its own CSA, or ask the manufacturer to revise the CSA to include that use. 

In all aspects of site investigations, health and safety considerations should take priority. Staff should be suitably trained and adequately supervised. Particular care should be taken with monitoring locations that pose particular difficulties for access or that are unsafe in any other way. Risk assessments should be prepared in advance and reviewed at regular intervals. Suitable personal protective equipment and emergency equipment and protocols should be available. 

Responds to the release of hazardous substances in a defensive manner without actually trying to stop the release. Requires Level 1 competency and 8 hours of additional training in basic hazard and risk assessment, personal protective equipment selection, containment and control procedures, decontamination, and standard operating procedures. 

Responds aggressively to stop a release. Requires 24 hours of Level 2 training and competencies in the following detailed risk assessment toxicology personal protective equipment selection advanced control, containment, and decontamination procedures air-monitoring equipment and the Incident Command System. 

Demonstrate readiness to apply professional skills to a range of emergency situations during regular drills (e.g., access, use, and interpret surveillance data access and use lab resources access and use science-based investigation and risk assessment protocols identify and use appropriate personal protective equipment). 

Having done the risk assessment, make sure that you wear personal protective equipment. Prepare all the crucibles, volumetric flasks, pipettes and beakers to be used, in advance, by soaking overnight in 0.5 M nitric acid. Then rinse three times with high purity deionised water and dry.
