Practicable reasonably

REASONABLY PRACTICABLE Thc implication that the quantum of risk is balanced against the sacrifice or cost in terms of money, time and trouble necessary to avert that risk. If the risk outweighs the sacrifice or cost, additional precautions are necessary. 

The provision and use of properly selected personal protective equipment is normally regarded as back-up for the previous measures. Refer to Chapter 13. In some situations it is the only reasonably practicable measure to ensure personal safety and its use may be a legal requirement. Examples are ... 

Total enclosure of the process and handling systems unless not reasonably practicable. 

For hazardous substances not classified as carcinogens, where protection of exposure is not reasonably practicable, adequate control should be achieved by measures odier than personal protection, so far as is reasonably practicable. Tliis is subject to the degree of exposure, circumstances of use of the substance, informed knowledge about the hazards and current technical developments. Any combination of the measures listed in Table 5.22 are applicable. 

Set out steps to be taken to prevent that exposure, or reduce it to the lowest level reasonably practicable. 

Preliminary All <0.1 X OEL 0.1-1.5 xOEL Some >1.5 xOEL None if exposures are as low as reasonably practical. Investigate and carry out a more detailed survey. Investigate, take remedial action and repeat survey. 

Berth operator to take reasonably practicable steps to control flammable or toxic gas escapes (e.g. hose support, flange couplings liquid- or gas-tight, drip trays). 

Requirements for work m confined spaces, including avoidance of entry if reasonably practicable, provision of a safe system of work and establishment of adequate emergency aiTangements. 

Requirements for the control of asbestos exposures at work. Exposure is to be prevented or, if this is not reasonably practicable, reduced to the lowest level reasonably practicable by measures other than the use of respiratory protective equipment. 

However, with practical samples the way the (k ) values of the individual components for any given complex solute mixture are distributed is not predictable, and will vary very significantly from mixture to mixture, depending on the nature of the sample. Nevertheless, although the values for the theoretical peak capacity of a column given by equation (26) can be used as a reasonable practical guide for comparing different columns, the theoretical values that are obtained will always be in excess of the peak capacities that are actually realized in practice. 

This system has proven to provide adequate levels of safety in the Gulf of Mexico and other similar areas where it is possible to abandon the location during a catastrophic event. In the North Sea where harsh environmental conditions exist, a different approach to safety has evolved which is based on developing a Safety Case and calculating an Individual Risk Rate (IRR) to show that the risk to any individual working in the facility is As Low As Reasonably Practicable (ALARP). 

Fully faired bicycles and faired adult tricycles are today the stuff of cutting edge inventors and hobbyists. Virtually all of them are recumbent bikes, because it makes sense to start out with a smaller frontal area to begin with. Some are reasonably practical for daily use, with lights, radios and ventilation systems others are pure race machines. 

Anyone who installs or erects any article for use at work must ensure that, so far as reasonably practicable, it does not constitute a risk to health and is safe for use. 

Work, etc. Act 1974 an employer has to take all steps, as far as is reasonably practicable, to ensure the health, safety and welfare of his workers. Permissible noise levels are defined by codes of practice, and the figure permitted for employee exposure is 90dB(A) 8-hour Leq. 

It is the duty of employers, as far as is reasonably practicable, to safeguard the health, safety and welfare of the people who work for them and others who may be affected. This applies in particular to the provision and maintenance of safe plant and equipment and methods of work, and covers all plant, equipment and substances used. Specific areas that require attention include ... 

Employers must, as far as is reasonably practicable, have regard for the health and safety of contractors employees or the self-employed who may be affected by the company s operations and for the health and safety of the general public. This covers, for example, the emission of noxious or offensive gases and dust into the atmosphere, or danger from plant and equipment to which the public or those not directly employed by the company have access. 

Some plant and equipment are immediately classified as confined spaces, but extreme caution is necessary in the assessment of other areas. Section 2 of the Health and Safety at Work, etc. Act 1974 requires employers to ensure the health and safety at work of their employees this duty is so far as is reasonably practicable. Therefore, as work in confined spaces is potentially dangerous this Section of the Act clearly requires employers to ensure that there is no risk to their employees when working in such an area. 

Attempt to ensure that residual and operational tensile or oscillatory tensile (fatigue) stresses in components are kept moderate so far as reasonably practicable. 

Remove significant environmental influences as soon as reasonably practicable, e.g. dewatering/dehumidification of produced oils and gases as close to wellhead as possible. 

Examine pressure heads and maximise whenever reasonably practicable to minimise vapour cavity formation. 

Maximum exposure limit (MEL) — the maximum concentration of an airborne substance, averaged over a reference period, to which employees may be exposed by inhalation under any circumstance. Thus, exposure to a chemical assigned an MEL must be as low as is reasonably practicable and, in any case, below the MEL. 

Once you have done your risk assessments, you must take the necessary action to remove or reduce the risk as far as is reasonably practicable. 

If for a carcinogen prevention of exposure is not reasonably practicable by using an alternative substance or process there is a requirement to apply all the measures fisted in Table 5.21. If these measures do not provide adequate control then suitable personal protective equipment as will adequately control exposure must be provided.
