Personal protection devices

AH operations producing dust require the usual measures to prevent dust in the atmosphere exceeding the allowable daily concentration. If this is not feasible, personal protection devices should be used. Especially when hydroquinone is present as a powder, adequate eye protection should be provided.

Universal precautions training that complies with the OSHA standard on occupational exposure to bloodborne pathogens, as well as a fire training program, should be provided on an annual basis for all laboratory employees. Personnel are required to use proper personal protective devices when handling corrosive, flammable, biohazard, or carcinogenic substances. Eye wash sta-...

Dr. A. Shaw at the University of Maryland Eastern Shore in Princess Anne, Maryland, is evaluating textile substrate for pesticide barrier effectiveness and comfort. Tests will be conducted to assess effectiveness of decontamination processes for these personal protection devices. Diazinon emulsifiable concentrates will be used to contaminate fabrics. Simulated wear studies will be conducted in the laboratory to assess the efficacy of these fabrics in protecting human health.

STOP includes five steps, especially, decide, cease, observe, act and report. Firstly, observation time and point is decided. Secondly, stop near personnel observed. Thirdly, it is observation. Observation content includes stuflF reaction, stuff position, personal protective device, tools and equipment, program and order. Fourthly, commurucation with stuflF observed. It is pay special attention to whether they know working routine and working order no blame. Finally, report. By STOP card report are finished.

Respiratory Protection To assess the safety of any particular operation, measurement of the solvent vapor exposure to workers in the area is recommended. If it is determined that the concentration in air is less than the recommended TWA for the solvent, no injury would be expected to workmen. If changes are made in the operation, which may result in an increase in concentration, duration, or frequency of exposure, measurements should be repeated. The degree of hazard can be minimized by containing the cleaning operation in an enclosed area, such as a hood, by ventilation that removes the vapors from the workroom air away from workers. The use of personal protective devices, such as gas masks, respirators, and self-contained or remote breathing apparatus, are not recommended for continuous use but can be effective for handling spills or similar upsets. 

Of these various factors, the most critical are the sound level, frequency, duration, and distribution of noise. The unprotected human ear is at risk when exposed to sound levels exceeding 115 dBA. Exposure to sound levels below 80 dBA is generally considered safe. Prolonged exposure to noise levels higher than 80 dBA should be protected against through the use of appropriate personal protective devices. 

The noise levels in most laboratories are usually not excessive, but there are laboratory facilities in which noise can reach levels forwhich hearing protection should be provided or the employees required to be involved in a hearing conservation program. It would be preferable, of course, if the noise levels could be lowered rather than to depend upon personal protective devices. 

The crew shall wear personal protective devices such as gas masks, face shields, hand gloves, protective industrial shoes boots, and protective aprons as per need. In case inflammable vapours are present, the shoes shall have mbber soles so that there is no sparking due to rubbing on hard floor tiles. 

Physical description. The physical description should include the state of the material (solid, liquid), the color, and the consistency (for solids) or viscosity (for liquids). For liquid materials, describe the clarity of the solution (transparent, translucent, or opaque). If an unknown material is a bi- or tri-layered liquid, describe each layer separately, giving an approximate percentage of the total for each layer. Afta- taking appropriate safety precautions for handling the unknown, including the use of personal protection devices, remove a small sample for use in the following tests.

Sand blasting of the surface may be permitted if sufficient personal protective devices and ventilation by Forced Draught (FD) fans, dust removal Induced Draught (ID) fans are used. However, workers should not enter the vessel when this is being done.

Personal protective devices have a serious limitation in that they do nothing to attenuate the hazard at source, so that if they fail and it is not noticed the wearer s protection is reduced and the risk he faces increases correspondingly.
