I recently received a question about when, and if, a receiving inspector should wear gloves. The questioner noted that in his facility, gloves appear to slow the receiving inspection process, so there is a potential negative to gloves.
ASA-100 (rev. 5.0) and FAA AC 00-56B both requires an accredited distributor to have receiving inspection procedures, but neither mentions gloves. So neither of these provides us with guidance about the glove question.
In the absence of formal guidance, a business must examine the likely the hazards and weigh the risks associated with both glove use and glove absence. We’ve been told that gloves can slow down receiving inspection, so the question is whether the potential benefits of gloves outweigh the effect on effectiveness and efficiency, and any other identified risks.
There are at least two reasons for receiving inspectors to wear gloves: to protect the receiving inspector and to protect the articles being inspected.
Protecting the Inspector
The first reasons for receiving inspectors to wear gloves is to protect the receiving inspector’s hands from harm. If the surfaces or materials being inspected could harm the inspector’s hands, then appropriate gloves should be worn.
The nature of “appropriate gloves” varies with the nature of the hazard that the receiving inspector reasonably faces, so it is important to perform a hazard identification and risk assessment process to identify what sort of protection might be necessary.
What is appropriate can vary. If the harm could come from chemicals, like battery electrolytes, then gloves designed to protect the hands from the chemicals should be worn. If the harm could come from sharp surfaces that might cut the hands, then the gloves may need to be heavy enough to provide protection from physical harm caused by the sharp surfaces. Temperature could also be a hazard: for example, a receiving inspector working with cryogenic liquids, like liquid oxygen, may need gloves to protect against the low temperature.
Likewise, the exterior coating of aircraft parts should be considered, because some parts bear a coating that can be dangerous. For example, chromate coatings can be carcinogenic.
It is important to review safety data sheets and other manufacturer’s recommendations when assessing the need for protective gloves. Remember, there are plenty of materials that should only be handled with gloves, but if the receiving inspector will only handle the packaging and not the material then the gloves may not be necessary for the receiving inspector.
Finally, be sure to examine actual hazards in the receiving inspection area, especially unusual hazards that are location-specific or business-specific. In a very small facility where welding must take place adjacent to the receiving inspection station, a prudent business may require that the receiving inspector wear protective clothing to protect against sparks and slag from the welding operation.
Protecting the Parts
The second reason for receiving inspectors to wear gloves is to protect the articles that are being received and inspected.
Gloves can be part of the strategy for protecting avionics or other sensitive equipment from electro-static discharge (ESD); but gloves are not the only way to approach ESD control.
Gloves are also normal for handling certain raw materials, like those used in composite repairs. The purpose of the gloves in this case is to prevent contamination of the materials.
In some cases, coatings on parts could be adversely affected by the oils on the skin. This is a corollary to the earlier warning about coatings adversely affecting the receiving inspector; the receiving inspector could also adversely affect the coating. Engine parts – especially hot-section engine parts – would be one type of part that might have specialized coatings (including subsurface coatings that could be revealed during a stripping process) that could be affected by oils from the skin.
In other cases, articles can be impaired by improper handling. Instructions for hot-formed acrylics typically call out gloves to prevent finger marks on the acrylic; whether this is necessary for a specific receiving inspection process depends on the hazards that may reasonably arise during the process.
To assess whether receiving inspectors should wear gloves is to protect the articles, the business should examine the range of articles that are typically received, identify any feature of those articles that might make then susceptible to damage or degradation as a consequence of non-gloved handling. If there are any such features, then the potential for damage or degradation can be treated as a hazard, and analyzed using risk assessment. The use of gloves can be considered as one candidate for risk mitigation, but th assessor should be open to other types of risk mitigation.
Conclusion
There is no explicit requirement for receiving inspectors to wear gloves. This means that the decision on mandating gloves within a business should be made based on risk mitigation criteria.
Ultimately, if your analysis shows that there are no hazard risks that need to be mitigated, or if it shows that there are better ways to mitigate those risks than the use of gloves, then mandating gloves might not be the right way to go. If, on the other hand, (1) there are identified hazards, (2) your analysis suggests that the risks posed by those hazards need to be mitigated, and (3) the use of gloves might reasonably mitigate those risks, then the use of gloves should be weighed against glove-related drawbacks, like loss of efficiency or effectiveness.
Assuming that the use of gloves might reasonably respond to identified risks in need of mitigation, then you should examine the potential drawbacks. If glove-related drawbacks, like loss of efficiency or effectiveness, seem to outweigh the benefits of using gloves, then it might be appropriate to try to identify other mechanisms for mitigating the identified hazards. If glove-related drawbacks, like loss of efficiency or effectiveness, are outweighed by the benefits of using gloves, then it might be appropriate to mandate gloves for the affected workers.
