Organizations can use a variety of processes to analyze workplace hazards and accident causal factors. Hazard evaluations and accident trend analysis can help improve the effectiveness of established hazard controls. Routine analysis enables an organization to develop and implement appropriate controls for hazardous processes or unsafe operations. Analysis processes rely on information collected from hazard surveys, inspections, hazard reports, and accident investigations. This analysis process can provide a snapshot of hazard information. Effective analysis can then take the snapshots and create viable pictures of hazards and accident causal factors. 

Workplace inspections tend to follow the same format but are given many different names including safety sampling, safety audits, safety inspections, hazard surveys, etc. Certain of the above are discussed below but all have the same aim - namely risk identification.

Today the demand for inspection of components with complex geometry, difficult access conditions or location in a hazardous environment is steadily increasing. Documentation, reproducibility and minimised health risk for the inspection staff are key issues. This leads to an increased demand for automated inspection, resulting in a need for new, advanced scarmer systems for NDE. 

Another application of laser-based profilometry is the inspection of rocket and missile components. The U.S. Air Force has funded work to develop a non-contact laser-based profilometer for the inside surface of solid rocket motors. Over time, these devices are subject to slumping and cracking, which could potentially render the rocket motor ineffective and hazardous. When fully implemented, this system will provide a meaningful screening method for evaluating the condition of aging rocket motors.

Mock OSHA Inspection. Maintenance can learn a lot about how the Occupational Safety and Health Administration (OSHA) trains thein inspectors and what is emphasized in an OSHA inspection. Some of the training of OSHA inspectors follows a program involving the recognition of potential hazards, avoidance of these hazards, and prevention of accidents (RAP). 

Risk-Based Inspection. Inspection programs developed using risk analysis methods are becoming increasingly popular (15,16) (see Hazard ANALYSIS AND RISK ASSESSMENT). In this approach, the frequency and type of in-service inspection (IS I) is determined by the probabiUstic risk assessment (PRA) of the inspection results. Here, the results might be a false acceptance of a part that will fail as well as the false rejection of a part that will not fail. Whether a plant or a consumer product, false acceptance of a defective part could lead to catastrophic failure and considerable cost. Also, the false rejection of parts may lead to unjustified, and sometimes exorbitant, costs of operation (2). Risk is defined as follows ... 

The impact forces on car couplers put high stresses in sills, anchors, and doublers. This may start fatigue cracks in the shell, particularly at the corners of welded doubler plates. With brittle steel in cold weather, such cracks sometimes cause complete rupture of the tank. Large end radii on the doublers and tougher steels will reduce this hazard. Inspection of older cars can reveal cracks before failure.

The selection of materials to be used in design dictates a basic understanding of the behavior of materials and the principles that govern such behavior. If proper design of suitable materials of construction is incorporated, the eqiiipment should deteriorate at a uniform and anticipated gradual rate, which will allow scheduled maintenance or replacement at regular inteivals. If localized forms of corrosion are characteristic of the combination of materials and environment, the materials engineer should still be able to predict the probable life of equipment, or devise an appropriate inspection schedule to preclude unexpected failures. The concepts of predictive, or at least preventive, maintenance are minimum requirements to proper materials selection. This approach to maintenance is certainly intended to minimize the possibility of unscheduled production shutdowns because of corrosion failures, with their attendant possible financial losses, hazard to personnel and equipment, and resultant environmental pollution. 

In order to overcome apprehension regarding erosion of turbine blades during service and the hazards attending such failure, provision is made for visual inspection by a strobe light and camera while in operation. Scheduled inspection by a camera (borescope) permits... 

Co., .- w,...ors should be stopped periodically to check for wear. The inspection may occur every few months. To accomplish this the compi sor must be stopped, blocked in, and purged if the gas is hazardous valve is removed from the cylinder and a feeler gauge inserted throi the valve opening. A measurement is taken between the lower side of piston and the cylinder wall. 

Inspect condition of cylinders regularly, especially those containing hazardous gases (e.g. corrosive). 

Guidance on the choice of respiratory protection for selected environments is given in Figure 13.6. All persons liable to use such protection should be fully trained this should cover details of hazards, limitations of apparatus, inspection, proper fitting of facepiece, testing, cleaning etc. 

You should be familiar with various occupancies and locations in your community where hazardous materials are used, stored, transported, or produced. To accomplish this familiarization, you must complete pre-emergency planning and inspection activities.
