Inspections hazard detection

Inspections Machines should have regularly scheduled inspections to detect potential problems early. Inspections should include regular checks and tests of guards and guard devices. Work orders should correct hazardous conditions or inadequate safeguards before returning a machine to use. 

Electrical/C I items Level gauges, transmitters, and switches for BPCS general instrumentation, power distribution, fixed hazard detection system. In most of the cases these are subject to regular inspection. 

Typical radiation in inspection and detection devices. Typically found in smoke detectors. Alpha particles pose a particular hazard through inhalation and ingestion. ... 

Self-inspections are typically done by the site safety manager and/or safety committee. These types of inspections are t3q)ically done an5rwhere from monthly to yearly, depending on how comprehensive they are. Self-inspections are a good way to ensure ongoing hazard detection as well as provide visibility for the safety effort. 

Regular involvement, walk-around inspections, informal spot checks, and specific topical discussions by line management and staff can be used to ensure that chemical reactivity hazard management systems and procedures are actually being implemented and followed on a day to day basis. Questions should be raised if unexpected changes have been made or unusual circumstances are detected. 

Routine inspections and housekeeping are valuable and important but may not detect major hazards. The independent search out of hazards by safety and health reviews is vital. 

When a process is accepted for examination, an inspection of the structures involved is performed. Any compounds with notoriously reactive substituents (e.g., nitro compounds) are, of course, subjected to ARC testing. Next, an oxygen balance is calculated to determine if enough oxygen is contained in the molecular structure to support combustion in a confined environment. If this is the case, the material in question is subjected to ARC testing. Finally, if no obvious hazard is detected, a train firing test is performed. 

During the operations phase, new hazards are identified by periodic inspections, worksite monitoring, audits, and appraisals. Techniques used to identify hazards during the operations phase include checklists, PET analysis, and safety studies. Accident analysis is also an important method of detecting previously undetected or uncorrected hazards. Accident analysis tools include change analysis, PET analysis, MORT and mini-MORT analysis, and event and causal factors charts. 

Who During demolition, a competent person shall conduct continuing inspections as the work progresses to detect hazards resulting from weakened or deteriorated floors, or walls, or loosened material. 

We have provided a checklist (Table 8.3.1.1) of things to look for, but the key is to keep your mind open to detect uncontrolled hazards. It is easiest to divide your inspection into the broad areas below and then get more detailed with specifics of each of these areas ... 

At many active workplaces, daily site inspections are performed by the supervisor in order to detect hazardous conditions, equipment, materials, or unsafe work practices. At other times, periodic site inspections are conducted by the site safety and health officer. The frequency of inspections is established in the workplace safety and health program. The supervisor, in conjunction with the safety and health officer, determines the required frequency of these inspections, based on the level and complexity of the anticipated activities and on the hazards associated with these activities. In a review of worksite conditions/activities, site hazards, and protecting site workers, the inspections should include an evaluation of the effectiveness of the company s safety and health program. The safety and health officer should revise the company s safety and health program as necessary to ensure the program s continued effectiveness. 

The supervisor or project inspector must perform daily inspections of active worksites to detect hazardous conditions resulting from equipment or materials or unsafe work practices. The supervisor, inspector, or site safety and health officer must... 

Preventive maintenance s ultimate purpose is to prevent accidents caused by vehicle deficiencies, machinery defects, or equipment hazards. Worn, failed, or incorrectly adjusted components can cause or contribute to accidents. Preventive maintenance and periodic inspection procedures help prevent failures from occurring while the vehicle/machine/equipment is being operated. Such procedures also reduce reliance on the operator, who may have limited skill and knowledge for detecting these deficiencies. 

Trend Analysis The process must include analysis of information such as injury/illness history, hazards identified during inspections, employee reports of hazards, and accident and near-miss investigations for the purpose of detecting trends. The results of trend analysis must be shared with employees and management and utilized to direct resources prioritize hazard controls and determine or modify goals, objectives, and training to address the trends. 

Internal safety inspections are important features in good safety practice. In daily production tasks, it is not always possible to detect all safety deficiencies. It is also well known that experienced employees can be too familiar with their work to note even imminent dangers. Regular walk-through surveys are therefore required. Safety checks may be conducted weekly, monthly or with some other level of frequency, depending on local risk conditions. It is usually advisable to use a checklist form appropriate to the plant, in order to conduct a systematic consideration of all of the relevant hazards. In the case of advanced safety inspection routines documented and issued using company systems, there is also a communication tool and checkout for the implementation of corrective measures by management. 

When the demand frequency is more than twice the periodic proof-test frequency, the application should be considered a high-demand mode application. Therefore the equations and techniques that use test interval as a key variable are not valid. In effect, one cannot take credit for periodic inspection unless it is done very frequently. Credit may be taken for diagnostics that cause the device to fail to the safe state (i.e. automatic process shutdown on any detected dangerous failure) in the high-demand case, as long as the diagnostic time period plus the time necessary to safely return the process to a safe state is less than the available process safety time (the time period between initiation of a demand and the hazard).
