Safety devices inspection

Does the facility have a program for regular inspection and testing of process safety valves and other process safety devices including interlocks ... 

Procedures for assurance of quality in the design, fabrication, installation, maintenance, testing and inspection for critical equipment are ) red. Safety requires that critical safety devices must operate as i led and process system components must be maintained to be able to contain design pressures. 

While boiler explosions fortunately do not occur too often today because of the existence of extensive safety devices as well as the regular program of inspection, their effects can be catastrophic. Similarly, sudden and unforeseen damage caused by the overheating of multi-tubular steam boilers due to lack of water can lead to eventual furnace collapse, with very extensive repair costs as well as lost production.

A steam gauge and water gauge are to be fitted to the boiler and the boiler and associate safety devices are to be inspected every 14 months. 

In no case should the interval between inspections of safety devices exceed the interval between inspections of the pressure vessels involved. 

Formal and systematic inspections of key equipment, safety devices, and safety interlocks. 

Recommended maintenance and inspection procedures for the safety devices must be provided per NFPA 86 (sect. 5-2.4 and Chapter 10). It shall be the responsibility of the user to establish, schedule, and enforce the frequency of, and the extent of, the maintenance and inspection program. Most of the critical safety devices are passive devices (they only react under abnormal conditions) therefore, they must be inspected frequently to prove that they are operational. Appendix B of NFPA 86 entitled, Example of Operational and Maintenance Checklist, provides examples of various checklists and inspection/maintenance procedures. 

Safety overview for all employees and new hires, common rules and procedures, heaith and safety control measures, protective devices, inspection, and emergency procedures. 

Ensure all emergency equipment and safety devices are operable at all times during hazardous operations. Before safety-critical, nonroutine, potentially hazardous operations are started, inspect all safety equipment to ensure it is operational, including the testing of alarms. 

Every employer must appoint a person to inspect and test the guards and safety devices on each press ... 

Statutory inspection of some key equipments has become due, and it is necessary to stop the plant, overhaul and repair (wherever necessary) and present to authorities for annual inspection as per the law, e.g. steam-generating boilers, pressure vessels, electrical installations, and safety devices. 

They are to be offered for inspection by statutory authorities (in a cleaned condition after removing all insulation) as per instructions on prescribed dates. Sufhcient safety devices are to be provided by law on each equipment which operates under pressure or is likely to develop pressure due to any reason, which stores or processes dangerous materials which can spill out or get ignited due to any reason. 

Those items (e.g. gas mask canisters, and personnel safety devices such as face shields and safety goggles) which are likely to deteriorate during long storage need to be checked once again before actual use. Some more examples arc electrical spares, catalyst used in reactors, spares of instmmentation, anti-caking agents, etc. If a proper inspection of such items is not done before use, it can result in serious problems in the process plant. 

The Occupational Safety and Health Act of 1970 established mandatory workplace characteristics backed by inspections and fines for non-compliance with OSHA s regulations. Under OSHA workers also cannot be expected to use information on job related health hazards to take injury avoidance measures on their own or to use personal safety devices if provided by the firm. Standards in turn require plantwide capital investments. The logic of mandatory health and safety standards for employers is that a government agency specializing in workplace safety will know more than employers and workers concerning how to make work sites safer. 

If variable speed fans are used, the revolutions should be checked with a tachometer. Safety devices must be regularly inspected (e.g. all chain and drive system guards must be correctly in place). Work outstanding as a result of safety visits should be assessed in order of importance and categories allocated for undertaking such work. 

Toxicity. Highly poisonous materials are difficult to handle industrially. Unless elaborate plant safety devices are planned, with frequent medical inspection of personnel, the more toxic substances must be avoided. 

Inspect your vehicle, equipment, and safety devices (i.e., reverse alarm, mirrors, and windows) at the beginning... 

Some states require annual vehicle inspections to help ensure that vehicles and safety devices are in proper working order. The assumption is that vehicles with working headlights, brakes, and other features will improve highway... 

The choice of interlocking method will depend on power supply and drive arrangement to the machine, the degree of the risk being protected against and the consequences of failure of the safety device. The system chosen should be as direct and as simple as possible. Complex systems can be potentially unreliable, have unforeseen fail-to-danger elements and are often difficult to understand, inspect and maintain. 

The Regulations deal with the appointment of competent persons for thorough inspections, examination and testing of the press and its safety devices, and the procedures to be adopted where defects are found. 

Following assembly and erection of hoists, and before being put in service, an inspection and test of all functions and safety devices shall be made under the supervision of a competent person. A similar inspection and test is required following major alteration of an existing installation. All hoists shall be inspected and tested at not more than 3-month intervals. The employer shall prepare a certification record which includes the date the inspection and test of all functions and safety devices was performed the signature of the person who performed the inspection and test and a serial... 

Equipment that has had modifications or additions which affect the safe operation of the equipment (such as modifications or additions invoiving a safety device or operationai aid, criticai part of a controi system, power piant, braking system, ioad-sustaining structural components, load hook, or in-use operating mechanism) or capacity must be inspected by a quaiified person after such modifications/ additions have been completed, prior to initial use. The inspection must meet all of the following requirements ...
