Skin adsorption is the most common route of exposure for lab workers. Because of this, choosing the right glove for your research is one of the most important laboratory safety decisions you can make. Not all gloves are equal and the material should be considered when making your choice. The following information will help determine your hazard and help you select an appropriate glove for protection.
|Step||What to do||How to do it|
|1||Identify the hazards of the materials being worked with||

The type of chemical to be used is the most important factor for selecting gloves. The chemical resistance of the glove is based on degradation, permeation, and exposure.
Degradation is the measurement of the physical deterioration of the glove due to contact with the chemical. The material may get harder, stiffer, softer, or may swell.
Permeation is the result of molecular diffusion of a chemical through a glove material.
Exposure is the length of time the glove will be in contact with the chemical. (Protection against splashes verses submersion in the chemical).
Using the Personal Protective Equipment (PPE) correctly is another link in the chain of keeping a person safe. If the PPE is not worn or used correctly then it may not offer the expected protection to the user. Below are guidelines for putting on (donning) and removing gloves (doffing), as well as the appropriate times and places to wear gloves.
- Wash hand before putting gloves on.
- Remove all jewelry from hands.
- Pick up one glove with the right hand.
- Line the thumb side of the glove up with the thumb side of the left hand.
- Slip the open end of the glove over the left hand and thumb.
- Stretch the palm side of the glove with the right hand, pulling the glove on to finger level.
- Position the fingers of the glove in line with the fingers of the left hand.
- Pull the remainder of the glove onto the left hand.
- Pick up the second glove with the gloved left hand.
- Line the thumb side of the glove up with the thumb side of the right hand.
- Slip the open end of the glove over the right hand and thumb.
- Stretch the palm side of the glove with the left hand, pull the glove on to finger level.
- Position the fingers of the glove in line with fingers of the right hand.
- Pull the remainder of the glove onto the right hand.
- Proceed with activity requiring gloves.
There are two standard methods to taking off gloves. Method One for glove removal is recommended, because it is harder for a person to become contaminated. However, if Method Two can be done without causing contamination, use the easiest method. Below are both methods.
- Grasp one of the gloves and cuff and pull it partway off. The glove will turn inside out. It is important to keep the first glove partially on your hand before removing the second glove. This protects you from touching the outside of either glove with your bare hands.
- Leaving the first glove over your fingers, grasp the second glove near the cuff and pull it part of the way off. The glove will turn inside out. It is important to keep the second glove partially on your hand to protect you form touching the outside surface of the first glove with your bare hand.
- Pull off the two gloves at the same time, being careful to touch only the inside surfaces of the gloves with your bare hands.
- Dispose of the gloves by placing inside out in the trash.
- Wash hands thoroughly.
- Grasp outside edge near wrist.
- Peel away from hand turning glove inside-out.
- Hold in opposite gloved hand.
- Slide ungloved finger under the wrist of the remaining glove, be careful not to touch the outside of the glove.
- Peel off from inside, creating a bag for both gloves.
- Wash hands thoroughly.
Do’s and Don’ts of Glove Use
- Work from clean to dirty—this will help prevent contamination
- Don’t touch your face or adjust PPE with contaminated gloves
- Don’t touch environmental surfaces – doorknobs, keyboards, computer mouse. This means when leaving the laboratory TAKE OFF YOUR GLOVES. If you need to wear a glove in the hallway to carry a sample, make sure that the gloved hand is carrying the sample and the non gloved hand is operating door handles, elevator buttons, etc.
- Change gloves when heavily soiled or if they are torn.
- Discard gloves after use, never wash or reuse disposable gloves.
Hand Lotion and Glove Use
Usually hand lotions that contain petroleum products are incompatible with latex gloves. The can accelerate the deterioration process which can increase penetration of chemicals and viruses. However, if you suffer from dry skin, there is hope with the following product.
