However, do not store laboratory chemicals near or under sinks where there may be exposure to water. Storage of cleaning supplies under sinks is acceptable. Ammonia cleaning products and bleach or sodium hypochlorite cleaning products are not compatible and must be stored separately.
Store in well-ventilated areas with secondary containment, such as a non-reactive plastic bin. Store below eye level. Store away from metal (unless the metal has a corrosion-proof coating). Store away from incompatibles and flammable materials.
Hazardous or Flammable Chemicals
Whether it is batteries, household bleach or other dangerous chemicals, or anything flammable, these are items that can spontaneously combust in the wrong conditions, so keep them in a garage, basement or laundry room in cool, dry conditions, where they can only be accessed by adults.
CDC guidelines do not support the storage of medical or surgical supplies under a sink. Other examples include reagent and chemicals that could have an adverse reaction if exposed to water/sewer/moisture, cleaned patient care equipment, etc.
Organic solvents should be collected in a container with a tight-fitting lid and labeled as hazardous waste. Corrosive liquids, such as strong acids and bases, should be disposed of as hazardous waste. However, if appropriately diluted to a pH between 5.5 and 10.5, these can go down the drain.
Chemicals that can be safely disposed down the drain include biological compounds and cellular constituents such as proteins, nucleic acids, carbohydrates, sugars, amino acids amines, nutrients, surfactants, and many metabolic intermediates.
There are three basic routes of disposal of laboratory chemical waste: Sanitary sewer or trash disposal of non-hazardous materials; Acid-base neutralization, followed by sewer disposal. Note:Any other type of treatment must be part of an experimental procedure to be considered legal; and.
Items not recommended to store under the sink
Harsh chemicals, bug spray, paper towels, waxes, carpet shampoo, drain cleaners, polishes and paints. Even some cleaning products, including dishwasher pods and colorful spray bottles, can be dangerous and entice curiosities for paws or tiny fingers.
All chemicals must be stored in a safe, secure location. Hazardous chemicals must be stored below eye level. Do not store chemicals on the floor, window ledges, or balconies. Keep containers closed unless you are dispensing a chemical or adding to the container.
If under your sink remains dry, you can store everyday products there—or in another easy-access spot, says Lubega. (Just make sure that the space is secure if there are children in the house.) Her main tip? Products should stay together.
Only explosion-proof or flammable material refrigerators should be used for storage of these chemicals within a laboratory environment. Refrigerated chemicals must be tightly capped to reduce vapors and alleviate odors. Flasks stoppered with cork, rubber, or glass should be wrapped with Parafilm to reduce leakage.
Wipe the surface with the bleach solution. To disinfect, allow the solution to stay on the surface for at least 10 minutes. Rinse and let the surface air dry.
Sodium hypochlorite should be stored separately from incompatible materials. Store chemicals such as reducing agents, organic materials and acids away from bleach. Sodium hypochlorite storage needs to be at temperatures below 68 F (20 C) in air-tight bottles.
Waste Disposal
If the bleach solution is at a household concentration or less, i.e., a maximum 10% concentration of sodium hypochlorite, and was used for disinfecting, limit discharges down a laboratory sink to less than 1-gallon (approx. 3.8 L).
Sodium Hypochlorite is the active ingredient in chlorine bleach. It is found in household bleach and many other disinfectants. Sodium hypochlorite reacts with ammonia, drain cleaners, and other acids.
Store bleach in a safe, cool, dry place. Keep away from direct sunlight and heat. Close the cap tightly after each use. If using it in the home, keep it away from children.
Keep storage areas free from clutter, explosives, and flammable conditions. Prevent chemical storage conditions that may encourage rats or pests. Place stored materials at least six feet from hoistways and at least 10 feet from exterior walls. Separate chemicals that cannot be stored together.
For example, acetic acid and ammonium hydroxide both start with “A” but are incompatible with each other, and should not be stored together.
Tip 1: Cleaning materials should always be stored out of the reach of children and pets. Tip 2: Install child-proof latches on under-sink cabinets in the kitchen and bathroom. Even if cleaning materials are no longer stored there, chemical smells may linger and could be dangerous to a child if they play under sinks.
Household Fluids
Household fluids include things such as household cleaners and car fluids. While these don't necessarily cause clogs in your pipes, these chemicals can be harmful when they are mixed into the water supply. If you're washing them down the drain, they will make it into the water.
Remove Personal Protective Equipment (PPE) such as gloves and lab coats before leaving the lab. Remove gloves before handling common items like phones, instruments, door knobs, etc. Keep all work areas clean and uncluttered. Wipe down benches with cleaners or disinfectants regularly.
Ensure container does not have free-standing liquid. Place container into clear plastic bag. Use tape or completed radiation tag to close bag. Secondary aqueous liquid waste within sink disposal limits may be disposed into designated and posted lab sink.
