What do gloves protect?
Gloves can offer protection against mechanical, chemical, thermal, biological, or electrical hazards, depending on their design and performance. These capabilities are not equivalent and cannot be determined solely by the material or thickness. Equipment suitable for one task may be insufficient or unsuitable for another that appears similar.
As personal protective equipment, it should be used when the risk cannot be avoided or sufficiently limited by other measures. Its selection does not replace guards, appropriate tools, automation, or product substitution. Nor does it make intervention on a machine safe when it requires shutdown and lockout/tagout before access.
Analyze the task and the risks
The selection process begins by identifying anticipated contact, its duration, intensity, and the areas requiring protection. Consideration should be given to whether sharp edges, hot surfaces, liquids, or specific agents are involved, and whether multiple hazards coexist. Equipment and product instructions help define requirements, but the final decision must be based on the actual working conditions.
Humidity, grip, precision, and change frequency are also important. If the glove makes it harder to control a tool or requires more force, it can introduce an additional strain. It’s advisable to test alternatives with users and observe the entire task, including setup, cleaning, and removal, rather than just checking how the equipment feels for a few seconds.
Chemical protection and usage time
For dermal exposure, product data and usage conditions should be consulted. Penetration, permeation, and degradation are distinct phenomena. Permeation can occur without visible rupture, so a glove that appears intact does not guarantee it will maintain its protective capacity against the contaminant.
The safety data sheet and manufacturer’s information provide guidance on material, thickness, and limitations. The breakthrough time measured in a test does not automatically equate to the safe duration of workplace use. Mixtures, temperature, flexing, and other conditions can alter performance, therefore an appropriate replacement criterion must be established.
Size, dexterity, and compatibility
The size should allow the equipment to be adjusted without excessive looseness or compression. The length must cover the necessary area and coordinate with sleeves or other protective gear. Protection also depends on how well the seal is maintained during movement, especially if there is a possibility of liquids entering the skin or contamination coming into contact with it.
Compatibility must be checked with tools and other equipment. When a task requires specific gloves and eye or face protection, the combination must allow work to be performed and removal to be carried out without contamination. Individual needs, such as sensitivity to certain materials, must be addressed with appropriate assessments and alternatives, avoiding leaving the hand unprotected.
Machinery and the risk of entrapment
Gloves can increase the risk of entrapment near moving parts. High tear resistance is not always an advantage in such an environment. Instructions and usage restrictions must be followed, and it should be assessed whether contact with moving parts could pull the glove and hand in.
Preventive measures are not about choosing a glove supposedly capable of resolving any snag. Dangerous access must be prevented, and interventions must be organized with appropriate precautions. If a procedure requires removing gloves for a specific operation, that decision must be based on an assessment that also considers other hazards associated with the task.
Practical example
A company uses the same disposable glove for handling packaging and cleaning with different products. The review reveals that it was chosen for convenience and price, without any data on its resistance to the most demanding cleaning agent. Since no holes are visible, it is reused for several applications.
The analysis identifies products, duration of use, and possible contact, consults technical information, and defines appropriate equipment and replacement frequency. It also improves dosage to reduce splashing. The example shows that the absence of visible damage and the generic name of the material do not replace a selection based on verifiable performance.
Use, Removal and Maintenance
The instructions must explain when to put on and change the glove, how to remove it without contaminating the skin, and what to do after an incident. Its condition must be checked before use, and it should be discarded if it is damaged or has lost its effectiveness. Reusable equipment requires cleaning and storage according to the manufacturer’s instructions.
They should not be repaired or decontaminated haphazardly. Management must ensure the availability of sizes and replacements, so that a lack of supply does not force prolonged use. Training and consultation with staff allow for the detection of fit issues, discomfort, and difficulties that affect effective use.
Common mistakes
Common mistakes include selecting gloves based solely on thickness, assuming any glove protects against chemicals, or interpreting a test level as unlimited protection. Other errors include reusing disposable gloves without authorization, ignoring incompatibilities with machinery, and requiring their use without providing sizes that allow for proper operation.
Effective protection combines technical selection, usage conditions, and monitoring. It should be reviewed whenever products, tools, or tasks change, and the information justifying the chosen equipment should be retained. The goal is to reduce exposure in a real and sustained way, without shifting the responsibility to the individual to compensate for an insufficiently controlled process by using gloves.
