Accident data current limitations

The chemical and physical hazards of the chemicals in the workplace. This is almost the same as the basic information on PELs and MSDSs hsted in the previous section. Those requirements basically defined limits of exposure and the sources of data. This requirement provides that the employees be given chemically specific hazard information on the chemicals in their work area. It is most important that the chemicals in actual use are the principal ones for which this information is provided. However, generic hazard information by class for chemicals present but not in use should be provided as well. There is always the potential for an accident involving chemicals not in current use. The employees must be informed that they are not to deface or remove the labels on commercial containers of chemicals, since they represent a primary source of information. It is not required by the standard, but following the requirement from the Hazard Communication Standard 29 CFR 1910.1200, that secondary containers intended for use beyond a single work shift should be labeled, it is highly recommended that this be required. 

Recent experimental data suggest that high bumup fuel may be more prone to failure during design-basis transients and reactivity insertion accidents than previously thought. Tests on the relationship between fuel failure enthalpy and bumup for pressurized water reactor fuel rods indicate lower failure initiation enthalpy thresholds (measured in differential calories/gram) than was crmsidered in the evaluation of currently approved fuel bumup limits. 

Current HSE fatality data indicates a UK rate of 10 (one fatality for every 10,000 actively employed construction workers per year). So actual fatalities due to construction activity do not appear to be unreasonable in relation to the HSE s tolerability limit. While zero fatality must always be the prime health and safety objective, the current level of fatalities taken alone, would not require that a special risk assessment be undertaken. Deaths arising from construction activity may not be at intolerable levels, but the position in regard to non-fatal accidents, both those causing major injuries and over-3-day injuries, is rather different. Current data here shows major incidents at an annual level of 10 (one major injury for every 1,000 actively employed construction workers per year). The data for over-3-day incidents indicates an annual level of 10 (one over-3-day injury for every 100 actively employed construction workers per year). 

Use the control chart on a routine basis to evaluate the SHE performance for new periods. Keep the control limits updated with accident and exposure data until the period before the last period. Avoid using data for more than five years back in time, or from earlier periods that for some specific reason are not representative of the current situation.
