Statistics like “your skin absorbs 60% of what you put on it,” and “anything you put on your skin is absorbed into your bloodstream within 26 seconds,” pop up frequently across the internet in forums, blog posts, infographics and even company websites3 .
Types of Chemical BurnsThe area will be red and painful, but there usually is no permanent damage. Partial thickness or second-degree burns extend into the second layer of skin called the dermis. You may have blisters and swelling, and it may leave scars.
Chemicals may cause serious damage not only to the outside of the body, but also to the inside.
Although your skin doesn't absorb chlorine, it's still possible for some to pass through. Too much chlorine in your bloodstream can be toxic. It's also possible to have an allergic reaction to bleach on your skin. Both chlorine toxicity and bleach allergies can lead to burns on your skin.
Chemical exposures to the skin can cause temporary or permanent health damage. Temporary skin damage may occur from exposure to chemicals. For example, many workers may experience dry, red, cracked skin from contact with water, soaps, gasoline, and certain types of solvents.
Dermal absorption is the transport of a chemical from the outer surface of the skin both into the skin and into the body. Studies show that absorption of chemicals through the skin can occur without being noticed by the worker, and in some cases, may represent the most significant exposure pathway.
There are four major routes by which a chemical may enter the body:
- Inhalation (breathing)
- Skin (or eye) contact.
- Swallowing (ingestion or eating)
- Injection.
If a chemical splashes into your eye, take these steps immediately.
- Flush your eye with water. Use clean, lukewarm tap water for at least 20 minutes.
- Wash your hands with soap and water. Thoroughly rinse your hands to be sure no chemical or soap is left on them.
- Remove contact lenses.
Sodium hydroxide (also known as lye) is one of the most corrosive of all bases. It generates significant heat when diluted and has an extremely high alkalinity (concentration of alkali elements in the solution).
Examples of corrosives:
- Glycolic acid.
- Imidazole.
- 4-Methoxybenzylamine.
- Sodium hydroxide.
- Amines.
- Sulfuric acid.
- Bromine.
- Hydrogen peroxide.
Liquid corrosive chemicals are those with a pH of 4.0 or lower or a pH of 9 or higher. Solid chemicals are considered corrosive when in solution; they fall in the above pH range. A highly corrosive chemical has a pH of 2 or lower or a pH of 12.5 or higher.
Sulfuric acid is dangerous because it is an extremely strong dehydrating agent. The corrosive action of acid on living tissues is due to the catalytic reaction of acid-base in ester and amide hydrolysis. The corrosive acids will react with the skin and hydrolyze the fats which are the chemical forms of esters.

Explanation: Acids and bases have various strengths, all depending on their pH . An extremely strong base would be more dangerous than a weak acid, and vice versa.
A corrosive material is a highly reactive substance that causes obvious damage to living tissue. Corrosives act either directly, by chemically destroying the part (oxidation), or indirectly by causing inflammation. Acids and bases are common corrosive materials.
An irritant toxic chemical causes reversible damage to skin or other organ system, whereas a corrosive agent produces irreversible damage, namely, visible necrosis into integumentary layers, following application of a substance for up to 4 hours. Corrosive reactions can cause coagulation or liquefaction necrosis.
All water contains some dissolved oxygen and is therefore somewhat corrosive. The rate of corrosion depends on many factors including the water's pH, electrical conductivity, oxygen concentration, and temperature.
What Are the Most Dangerous Household Chemicals?
- Antifreeze. Swallowing antifreeze (ethylene glycol) may cause damage to the heart, brain, kidney and other internal organs.
- Bleach. Being a strong corrosive substance, bleach can affect the respiratory system if inhaled.
- Drain cleaners.
- Carpet or upholstery cleaners.
- Ammonia.
- Air fresheners.
Below, we list the 19 most dangerous items you might have in your home, and the damage they can cause.
- Non-Stick Cookware.
- Flea and Tick Products.
- Mothballs.
- Air Fresheners.
- Oven Cleaner.
- Furniture Polish and Stain.
- Toilet Bowl Cleaner.
- Gas Space Heaters.
Most standard sources recommend that water rinsing/flushing following skin or eye contact with a chemical should continue for 15 or 20 minutes. However, all chemicals do not cause the same degree of effects (some are non-irritants while others can cause severe corrosive injury).
Wash your hands thoroughly with dish soap and water, whether ammonia remains or not. Pour a heavy amount of soap over your hands and wash them thoroughly with the soap. Scrub gently and remove any remaining traces of the ammonia.
Clothes that are billed as "waterproof," "stain resistant," or "wrinkle-free" often contain chemicals that have been linked to adverse health effects. Many clothing items, such as blue jeans, also carry a dye that can release cancer-causing chemicals.
Many cleaning supplies or household products can irritate the eyes or throat, or cause headaches and other health problems, including cancer. Some products release dangerous chemicals, including volatile organic compounds (VOCs). Other harmful ingredients include ammonia and bleach.
Substances that cause irreversible damage to and destruction of the skin are classified as “corrosive.” In the process of permanently damaging the skin, corrosive substances also cause it to swell and become discolored, eventually forming bloody scabs as it dies.
Safe storage of household chemicals
- Store flammable liquids preferably outside in a metal cabinet or in an unheated area. Never store near an open flame or spark.
- Store corrosive materials in a place such as a plastic tub or tray where the product can't spill out if the container leaks.
- Store out of the reach of children and pets.
Although each
spill response is unique, there is a series of
steps that can be taken during every
response.
Seven Step Spill Response for the New Responder
- Step One: Assess the Risk.
- Step Two: Protect Yourself.
- Step Three: Confine the Spill.
- Step Four: Stop the Source.
- Step Five: Evaluate and Implement Cleanup.
- Communicate the hazard. Immediately notify others working in the area and any supervisory personnel of the hazard, and if the situation warrants it, evacuate the area.
- Control the spill. This step focuses on ensuring that the spill does not become any worse.
- Contain the hazard.
- Clean up the spill and any damage.
Bases have a bitter or astringent taste and a pH greater than 7. Common bases are sodium hydroxide, potassium hydroxide and ammonium hydroxide. Bases are neutralized by using a weak acid.
These steps along with the correct equipment and training will ensure that spill response is both fast and effective.
- Assess the risk.
- Select personal protective equipment (PPE)
- Confine the spill.
- Stop the source.
- Evaluate the incident and implement cleanup.
- Decontaminate.
- Complete required reports.

Remove or isolate incompatible materials as well as other hazardous materials. Methods for Containment and Clean-up: Contain and soak up spill with absorbent that does not react with spilled product. Shovel or sweep dry sodium hydroxide for recycling or disposal. Flush spill area.
Pour baking soda directly onto any acid spill. This will neutralize light acids like vinegar or even strong, dangerous acids like muriatic and sulphuric acids. Douse the entire affected area with the baking soda (sodium bicarbonate, NaHCO3) to neutralize the acid.
A simplified spill response plan might look like this: Evacuate personnel from the immediate area of the spill. Identify the spilled material(s) Barricade the spill area and notify others in surrounding areas. Extinguish or disconnect all sources of ignition and contact the fire department if the chemical is flammable.
Acid Spills (hydrochloric or sulfuric acid):Neutralize spill with sodium bicarbonate/baking soda 2. Wait until bubbling/fizzing has stopped 3. When using a neutralizing spill kit, the kits are buffered and will not have a bubbling action.
