chemical storage cabinet Philippines
Chemical Storage Cabinet Philippines Specialized types of storage cabinets must be used in laboratories in order to separate incompatible chemicals from one another and to ensure safe storage. All chemicals must be stored in a secure container, preferably within enclosed cabinets. Periodically check shelves and supports in all chemical storage cabinets for corrosion or other signs of damage.
Chemical storage devices are usually present where a workplace requires the use of non-hazardous and/or hazardous chemicals. Proper storage is imperative for the safety of, and access by, laboratory workers. Improper chemical storage can result in the creation of workplace safety hazards, including the presence of heat, fire, explosion and leakage of toxic gas.[1]
Chemical Storage Cabinet Philippines are typically used to safely store small amounts of chemical substances within a workplace or laboratory for regular use. These cabinets are typically made from materials that are resistant to the chemicals stored in them and occasionally contain a bunded tray to capture spillage.
Chemical stores are warehouses commonly used by chemical or pharmaceutical companies to store bulk chemicals. In the US, the storage and handling of potentially hazardous materials must be disclosed to occupants under laws managed by the Occupational Safety and Health Administration (OSHA).
Proper labeling is important to ensure that chemicals are not misidentified, which is key to protecting health and safety. For example, organizing chemicals alphabetically is not generally recommended, because it may lead to incompatible chemicals placed near each other, risking a dangerous reaction.
Instead chemicals should be stored according to their reactivity and other properties. For example, acids and bases are incompatible and should be stored separately, whereas sodium and potassium can be kept together as they are both water-reactive but do not have any added hazard when placed with one another.[2] The United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS) is an international system created by the United Nations to classify chemicals.[3] The Safety Data Sheet (SDS) or Material Safety Data sheet (MSDS) identifies and classifies the properties and hazards of chemicals.[3]
Unnecessary storage of large amounts of chemicals can pose a hazard if the amount exceeds the limits permitted by laboratory guidelines, and is avoided by accredited workplaces and laboratories. Chemicals are usually stored in cool areas, away from direct heat sources, moisture, or light and should be regularly checked for degradation or damage.
The safe storage of hazardous chemicals is an essential part of laboratory safety. Chemical storage is complex—there is no one-size-fits-all plan to store chemicals—but there are regulations, campus requirements, and best practices that can guide the process. The general concept is to prevent chemicals from causing harm to people, property, other chemicals, or the environment.
In order to fully understand the hazards associated with stored chemicals you first need to know what chemicals are being stored. Safe storage begins with an up-to-date inventory of chemicals and knowledge of the hazards posed by each chemical.
Due to chemicals’ varying properties, many types of facilities are needed. Chemical storage facilities must be adequately maintained to prevent and mitigate their hazards. Accidental spillage or mixing of chemicals can be hazardous.
General Storage Requirements:
All chemicals must be stored in a safe, secure location.
Shelves should be level, stable, and secured to the wall or another stable
Store chemicals away from direct sunlight, sources of heat, and egress pathways
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.
Provide secondary containment for liquids whenever possible. Dishpans or polyethylene trays work
Don’t store chemicals in a sink or fume hood, except for certain toxic gases that are so dangerous they can only be stored in a gas cabinet or fume
Label containers, and be sure container is compatible with the chemical
Use rated storage cabinets or safety cans whenever possible—required for >10 gal. of flammables.
Cold rooms, refrigerators, and freezers have additional requirements, particularly for flammables.
Shelving
Shelving must be stable, constructed of a material that is compatible with the chemicals stored on it, and not loaded beyond its rated capacity.[4] It is recommended not to store heavy containers on the highest shelves. Storing chemicals under a sink is not recommended, with the exception of compatible cleaning agents and non-hazardous chemicals.
Cabinetry
Chemical storage cabinets are usually suited for specific classes of chemicals. Acid cabinets, for example, consist of corrosion-resistant materials and sealing to prevent the leakage of fumes. Some institutions recommend a tray to contain any spillage and regular checks for any sign of corrosion. Flammable solvent cabinets are produced from specialized wood or metal able to resist fire for at least 30 minutes. [5] For example, a flammable liquid is any liquid that has a flash point lower than 93 °C (199 °F). Corrosive storage cabinets are designed for storing corrosive or oxidizing liquids. They contain a single-piece, leak-proof floor pan to contain spills, must be vented to the fume hood or the lab exhaust system, and their interior is constructed of corrosive-resistant materials. Wooden cabinets provide excellent strength for storing corrosives. Their laminate finish offers a high level of chemical durability.
Desiccation
Desiccation is a chemical storage technique used to maintain or to regulate humidity, usually to store moisture-sensitive chemicals. Desiccation is generally performed with a desiccator. Several types of desiccators are available, including standard, automatic, gas purge and vacuum desiccators.
Cold storage
Refrigerators and freezers can be used to store flammable and hazardous chemicals. In most situations, specialized laboratory refrigerators are used to ensure that the flash points of certain chemicals are not reached. For flammable chemicals, explosion-proof equipment must be used because conventional refrigerators have sources of ignition.[
Maintaining the proper condition of chemical storage areas reduces the likelihood of accidents or injuries in the workplace. For example, work areas should always be kept neat and clean and regularly inspected for any hazards such as improperly cleaned residue.
