Wearing gloves protect you against skin absorption of chemicals, chemical burns, thermal burns, and cryogenic liquid exposure. So, choosing the appropriate hand protection can be challenging in a laboratory setting.
When wearing Diamond nitrile pest control gloves, chemicals of unknown toxicity, corrosive materials, and boiling and cold materials. Disposable nitrile gloves are usually appropriate as they protect against accidental splashes or contact with lab chemicals. However, it should be consulted to verify chemical compatibility with the gloves.
You were working with chemicals with high acute toxicity and working with corrosives in high concentrations. You can handle chemicals for extended periods or immerse a part of your hand into a chemical. The appropriate glove material should be selected based on chemical and task compatibility.
Consider the following when selecting a glove:
1: Degradation Rating.
2: Breakthrough Time.
3: Permeation Rate.
The change in a glove’s physical properties is caused by contact with a chemical. It typically appears as hardening, stiffening, swelling, or cracking of the glove. Degradation ratings indicate how well a glove will hold up when chemical exposure.
2: Breakthrough Time
Breakthrough time is the elapsed time between the test chemical’s initial contact on the glove’s surface. And the analytical detection of the chemical on the inside of the glove.
3: Permeation Rate
It is the rate at which the test chemical passes through the glove material once a breakthrough has occurred and equilibrium is reached. The term permeation involves:
- Absorption of chemicals on the glove’s surface.
- Diffusion through the glove.
- Desorption of the chemical inside the glove.
If chemical breakthroughs don’t occur, the permeation rate is not measured well.
Manufacturers stress that permeation and degradation tests are done under laboratory test conditions. Thus, it can vary significantly from actual conditions in the work environment. For mixtures, it is recommended that the glove material be selected based on the shortest breakthrough time.
Fine skill is needed and cannot be achieved with a manufactured product. Then you need to consider double gloving with a less compatible material and replacing the outer glove if there are any signs of contamination. In some cases, such as wearing silver shield gloves, it may be possible to wear a tight-fitting glove over the loose glove to increase agility.
It is usually measured in mils or gauges. And a gauge glove is equivalent to 10 mils. These are thinner, lighter gloves and offer better touch sensitivity and flexibility. It may provide shorter breakthrough times and doubles the thickness of the glove.
Glove length should be chosen based on the depth to which the arm will be immersed or where chemicals splash is likely. Gloves longer than 14 inches provide extra protection against splash or immersion.
Glove size may also be essential; indeed, one size doesn’t fit all. Gloves that too tend to cause fatigue and are loose can make it more difficult.
Thus, the circumference of the hand, measured in inches, is roughly equivalent to the reported glove size. And the glove color, cuff design, and lining should also be considered for some tasks.
Glove Inspection, Use, and Care
One can inspect gloves for signs of degradation or puncture before use, and you need to test for pinholes by blowing or trapping air inside and rolling them out. Try not to fill them with water, as this can make the gloves uncomfortable and make it more difficult to detect a leak when wearing the glove.
It would help if you changed disposable gloves immediately when you find any sign of contamination. Diamond Dotted All Purpose Gloves should be washed frequently if used for an extended period.
Try not to wear gloves outside the laboratory and utilize carts or carriers to transport research materials from the lab to the other support areas. If materials must be hand-carried, you should wear gloves for touching door knobs, elevators, buttons, etc.
It would help if you were careful not to handle anything but the material involved in the procedure while wearing gloves. So, touching equipment, phones, or other surfaces may cause contamination, and resist touching your face, hair, and clothing.
Before removing them, you need to wash the outside of the glove, and to avoid accidental skin exposure, remove the first glove by grasping the cuff and peeling the glove off the hand. You can repeat the process a second hand. And touch the inside of the glove rather than the outside. Also, you need to wash your hands immediately, either with soap or water.
Proper Glove Removal
Gloves should be removed to avoid skin contact with the glove’s exterior and possible contamination. Disposable gloves should be removed as follows:
1: Grasp the exterior of one glove with your gloved hand.
2: Carefully pull the glove off your hand and turn it inside out; the contamination is now on the inside.
3: Ball the glove up and hold it in your other gloved hand.
4: Slide your ungloved finger into the opening of the other glove and avoid touching the exterior.
