What containers are used to store acids?
Acids are typically stored in glass containers because some acids will destroy plastics or react with them forming inedible products as these plastics are modified petroleum products and hence, corrode the plastic vessels easily. Glass on the other hand is not corroded by these acids so they are a good option.

Acids should be segregated from bases and active metals such as sodium, magnesium and potassium. Acids should be stored in chemical resistant trays that are capable of containing any spillage or leakage from their container.
Are acids stored in metal containers?
Acids are corrosive in nature. They can react with metals and corrode them, that's why acids are not stored in metal containers.
Are acids and bases stored in beakers?
Glass bottles are ideal for storing most acids and bases. Ordinary glass is largely inert and does not react chemically with most substances, including aqueous substances like acids and bases. It is also nonporous, which means it will not absorb or contaminate chemicals.
Why are acids stored in steel containers?
This is partly because these plastics are chemically inert and so won't react with the substance. Metal containers, on the other hand, are significantly more chemically reactive than other materials like plastic or glass.
How do you store acid waste?
Use waste containers with leak-proof, screw-on caps so contents can't leak if a container tips over. Corks, parafilm, and beakers are not acceptable. If necessary, transfer waste material to a container that can be securely closed. Label the new container.
What acids should not be stored together?
6. Incompatible acids must not be stored together. (Examples: perchloric acid is not to be stored with a reducing agent such as sulfuric acid, as upon mixing, this could produce a shock sensitive explosive; nitric acid and acetic acid, a potential explosive mixture, must not be stored together.)

What is the best practice to minimize the quantities of hazardous chemicals on hand whenever possible?
It is best practice to minimize the quantities of hazardous chemicals on hand whenever possible. Minimization of stored chemicals is a key way to reduce the likelihood and severity of an incident involving said chemicals. Chemical storage limits, from various regulatory bodies and campus policy, are outlined in Appendix D of the campus Chemical Hygiene Plan. It is important to note that storage limitations, particularly based on fire code, often extend to large groupings of labs or even entire floors of buildings. Each space is different, so contact Chemical Safety staff for an evaluation.

What Is a Flammable Cabinet?
A flammable cabinet is designed to safely store potentially flammable or combustible liquids. Instead of storing such hazardous materials on an exposed shelf, a flammable cabinet allows you to store flammable or combustible liquids in a container that is designed to prevent fires and smother flames.
What is the boiling point of flammable liquid?
The Occupational Safety and Health Administration (OSHA) defines a flammable liquid as “any liquid having a flashpoint at or below 199.4ºF and having a boiling point at or below 95ºF.” These flammable liquids are then divided into four categories based on different ranges of flashpoints and boiling points. A liquid’s flashpoint reflects its volatility (ability to generate vapor) and is necessary to know in cases where the vapor of the liquid, not the liquid itself, may burn and cause a fire.
How long does it take for a flammable cabinet to withstand a fire?
Flammable cabinets are constructed to withstand a 10-minute fire test. During the test, the cabinet doors must remain closed, and the internal temperature of the cabinet must not exceed 325ºF.
