How to protect your hands, eyes and lungs when working with hot peppers

Wear rubber, latex or nitrile gloves every time you cut hot peppers, keep your hands away from your face until the gloves are off and your hands are washed, and cook with a window open or the range hood running [1]. Add eye protection when you blend or simmer superhots, and wash knives, boards and the blender in hot soapy water before anyone else uses them. The burn can show up hours after you finish, so prevention beats any remedy [2]. At production volume, if a respirator becomes necessary, federal workplace rules require fit testing and a written program [3]. Here is what to use for each part of the body and why.

Why pepper burn catches people out

The heat in a pepper comes from capsaicin and related compounds, which sit mostly in the pale inner membranes and in smaller amounts in the seeds [4]. Capsaicin irritates skin, eyes, the stomach and, when it is in the air, the lungs [1]. Three features make it easy to underestimate:

• It is delayed. In a 2025 case report, a woman chopping home-grown chiles for the first time felt the burning begin a couple of hours after she finished cooking. It reached 7 out of 10 for pain and lasted several hours [2].
• It does not rinse off easily. Capsaicin dissolves poorly in water. The same patient washed repeatedly with cold water and mild soap, and washing with shampoo made the pain worse [2].
• It travels. Whatever is on your fingers ends up on a phone, a door handle, a contact lens or a child's face.

What capsaicin is and how it works on the body are on Where the heat comes from.

Hands: choosing and using gloves

Every extension and poison-control source checked for this page tells cooks to glove up for hot peppers. They differ only in which materials they name.

Glove habits that matter more than the brand

• Put them on before the first cut and leave them on until the peppers, the board and the knife are cleaned up.
• Change a torn glove at once. A small tear lets juice in and holds it against your skin.
• Take them off inside out, peeling from the cuff, so the outside never touches your skin.
• Wash your hands after anyway. The National Center for Home Food Preservation's advice for anyone who skips gloves is to wash thoroughly with soap and water before touching the face or eyes [5]. Do the same with gloves, since juice gets past cuffs.
• Use the glove hand for peppers only. If you need your phone or the tap, take a glove off.

Superhot and dried peppers

Habaneros, scotch bonnets, ghost peppers and the superhots carry far more capsaicin than a jalapeño. For these, use nitrile with a longer cuff or double-glove so you can strip the outer pair when it gets messy. Ground or crushed dried chiles are worse in one way: the dust goes airborne. Handle powders gently, away from your face, and treat them like the fume section below.

Eyes: protection for the messy steps

Rubbing an eye with a pepper finger is an easy mistake to make. Gloves prevent most of it. For the steps that throw juice or vapor, add eye protection.

• When to wear it: cutting superhots, blending a hot batch, straining with force, lifting the lid off a simmering pot of superhots, and grinding dried chiles.
• What to wear: close-fitting safety goggles or splash goggles. Everyday glasses help with splashes but not with vapor.
• Contact lenses: take them out before a heavy prep session, or switch to glasses for the day. Capsaicin on a fingertip transfers straight to the lens when you take it out later.
• If it happens anyway: go to Pepper burn first aid. Poison Control's first step for eyes is warm water for 15 minutes [1].

Lungs: ventilation and superhot fumes

Simmering or blending hot peppers puts capsaicin into the air, which is why a whole household can start coughing when one person cooks a pot of habanero sauce. Poison Control warns that inhaled capsaicin can trigger an asthma attack or breathing trouble in susceptible people and advises open windows or fresh air when preparing or cooking hot peppers [1]. In practice:

1. Ventilate first. Run the range hood on high, vented outdoors if you have one, and open a window to make a cross draft.
2. Keep the lid partly on while simmering, tilted away from you.
3. Let the pot cool slightly before blending, as the NCHFP recipe directs [5]. Hot liquid throws more vapor.
4. Open the blender lid away from your face, and wait a few seconds before looking in.
5. Keep children, pets and anyone with asthma out of the kitchen while you cook superhots.
6. Move outdoors for very large or very hot batches: a camp stove or side burner on a patio takes the fumes out of the house.

Anyone who has trouble breathing or chest discomfort after exposure needs 911 [1].

Knives, boards and the blender

Capsaicin left on tools ends up in the next meal and on the next person's hands.

• Wash right away in hot soapy water while still gloved. Scrub board surfaces with a brush; knife grooves and scratches on plastic boards hold residue.
• Keep a pepper board if you make sauce often. A dedicated board takes away the risk of habanero on tomorrow's fruit salad.
• Blender: fill halfway with hot water and a drop of dish soap, run it for 30 seconds, empty, then wash the jar, lid and gasket by hand. Rinse and run again with clean water.
• Sponges and towels: wash them after a heavy session, or use paper towels for wiping juice.

At production volume: when the kitchen needs more than gloves

When you scale up to kettles of habanero sauce or bins of dried chiles in a shared kitchen or your own facility, the exposure is longer and the air carries more capsaicin. If anyone else is working for you, federal workplace safety rules apply.

Controls in order

OSHA's respiratory protection standard (29 CFR 1910.134) puts engineering controls first: ventilation, enclosure or other ways of keeping the contaminant out of the air. Respirators are for when those controls are not feasible or while they are being installed [3]. For a sauce maker, that means a properly sized hood over the kettle, lids on kettles, cooling before blending and scheduling superhot runs when the fewest people are in the room.

If respirators are required

When an employer requires respirators, the standard requires [3]:

• A written, worksite-specific respiratory protection program and a named program administrator.
• NIOSH-certified respirators.
• A medical evaluation by a physician or other licensed health care professional before fit testing and use.
• Fit testing for any tight-fitting facepiece before first use, whenever a different facepiece is used, and at least once a year.
• Training before first use and every year after.
• Respirators, training and medical evaluations at no cost to the employee.

Voluntary use

If an employee chooses to wear a filtering facepiece (a disposable dust mask such as an N95) when it is not required, no full program is needed, as long as the employer decides the mask itself creates no hazard. The employee must still be given the information in Appendix D of the standard [3]. Voluntary use of any other kind of respirator needs the program elements that confirm the person is medically able to wear it [3].

These rules apply to employees. If you are hiring your first helpers, training them on safe handling belongs alongside training on the sauce's critical factors; see Hiring help.

If the burn gets through anyway

Even careful cooks get caught. Pepper burn first aid gives Poison Control's steps for eyes, skin, mouth and breathing, what did not help in the reported cases, and when to call Poison Control at 1-800-222-1222 or 911.
