Hazard controls, adequate

Acceptable Exposure formation adequate to develop Access to the Hazard Controls ... 

These processes cause considerable wear on the machines. Heat generation, particularly when grinding vulcanisate, can be a fire hazard unless grinding and storage is controlled adequately. 

Develop Procedures and Training. Not all hazards can be controlled within the software subsystem. Providing adequate hazard controls is a system level issue that includes the control of physical hazards from all areas, and minimizing risk resulting from environmental conditions. Where it is impractical to eliminate hazards through design, procedures and training must be used. All software-related functions that affect service should be documented, and users should be fully trained. 

Safety basis Safety basis means the documented safety analysis and hazard controls that provide reasonable assurance that a DOE nuclear facility can be operated safely in a manner that adequately protects workers, the public, and the environment. 

If the hazard control measures (engineering or PPE) are not adequate to prevent exposure and provide an acceptable level of safety, laboratory management should not permit the experiment or procedure in question, and should explore whether a safe substitute for COCs can be identified. 

Compliance with design-based safety standards does not necessarily ensure adequate safety in complex or state-of-the-art systems. It often is necessary to perform hazard analyses to identify hazards that are specific with the system, and develop hazard control measures that adequately control the associated risk beyond those that are covered in existing design-based standards. 

Do the work practice controls and administrative controls adequately address those hazards not covered by engineering or administrative controls ... 

Are followup studies (where appropriate) conducted to ensure that hazard controls were adequate ... 

Use of Results Sampling results must be used to identify areas for additional, more in-depth study, to select hazard controls, and to determine if existing controls are adequate. 

This will allow some planning in terms of hazard control measures in initial stages. A final report should provide you with clear recommendations which are likely to adequately control the hazard when implemented. It will also act as a record of assessment which should be kept by the organization. 

Through adequate inspection and maintenance programs and existing hazard control systems are properly maintained so that they eliminate or... 

In the most effective safety cultures, everyone is involved in monitoring hazard controls in the workplace. It s not usually adequate to simply rely on the safety director or safety committee to monitor hazard controls. Employees and supervisors, especially, need to be directly involved in this activity. 

Some pieces of work equipment involve specific risks to health and safety where it is not possible to control adequately the hazards by physical measures alone, for example, the use of a bench-mounted circular saw or an abrasive wheel. In all cases the hierarchy of controls should be adopted to reduce the risks by ... 

One of the main purposes of a COSHH assessment is to control adequately the exposure of employees and others to hazardous substances. This means that such substances should be reduced to levels which do not pose a health threat to those exposed to them day after day at work. Under the 2005 amendments to the COSHH Regulations 2002, the Health and Safety Commission has assigned workplace exposure limits (WELs) to a large number of hazardous substances and publishes... 

All other hazardous substances which have been assigned a WEL. Exposure to these substances by inhalation must be controlled adequately to ensure that the WEL is not exceeded. These substances were previously assigned an occupational exposure standard (OES) before 2005. For these substances, employers should achieve adequate control of exposure by inhalation by applying the principles of good practice outlined in the approved code of practice and listed below. 

The hazard resolution process is a critical component of the SMS. If employees and OSHA (or other regulatory) inspectors are to feel secure that the firm is following a sane safety program, it is important to explain how hazards are resolved. How are hazards controlled Who has signature authority verifying that the hazard is controlled adequately Many corporations use the system safety committee as a controlling body. 

No verification that hazard controls are adequate and in place. 

Once, working on a two-phase flow systan, we needed to make sure that it was two-fault tolerant to an accident—in other words, after two failures, the system was still safe. We put in two relief valves to handle overpressure. The problem was they both had to operate in tandem to handle the flow and pressure profiles. That was an important example of validating that the hazard control is adequate. Obviously, the two relief valves weren t independent in their operations and therefore didn t independently control the hazard. Luckily, we validated our control was NOT adequate during testing and resized the relief valves. 

The last step is to conduct follow-up activities. It is important to monitor the system to ensure the effectiveness of the hazard controls and to check for new or unexpected hazards. Things change so it is important to periodically reassess the systan and determine if hazards are still adequately identified and control mechanisms stiU work. This is especially important if the system is modified, expanded, or reconfigured or operating conditions change. If there are any material changes to the system, then the hazard analysis should be updated to reflect the changes and their impacts to the system. 

If changes are made to the system, they must be reviewed and approved by the appropriate engineering disciplines. And lastly, the company must follow up on the changes to verify that the hazard control is implemented and adequate. Remember that when thinking about changes to the system, use the hazard reduction precedence described in Chapter 2 as your guide. 

Software change analysis Software changes are constant in the development and deployment of software systems. Configuration control is the only way to ensure that you know how the software has been modified. In this stage of the software safety process, you must also verify that software changes do not invalidate hazard controls or create a hazardous condition. And, this all must be adequately documented, not just the changes but also the implications to the changes. 

The accident report should be put online (in the safety knowledge management system, see Chapter 10) so that all accident statistics can be tracked. This will allow you to trend useful information to determine if the hazard controls are adequate or if there is some underlying problem that has not been resolved. 

Once MSD hazards have been identified, the next step is to eliminate or control than. An effective hazard control process involves identifying and implementing control measures to obtain an adequate balance between woricer capabilities and work requirements so that MSDs are not reasonably likely to occur.
