Electrical Accessories to Keep You Powered On

U.S. Chemical provides several electrical accessories to help safely manage and maintain a reliable power supply to your chemical storage building. Providing electricity to the devices and units you need to operate keeps the integrity of your hazardous compounds high and increases production capacity.

Factory Electrical Installation

During manufacturing, our experienced team installs electrical items and runs conduit. We ensure junction boxes, conduits and circuit breakers are properly sized by engineering, and wiring and breakers are per electrical schematic drawings based on NEC and manufacturers recommendations. All equipment boxes, electrical accessories, and electronic devices mounted on exterior of building are rated for outdoor use. Distribution panels are always labeled and any metal parts which may become energized are bonded.

Electrical Quality Assurance

The U.S. Chemical Storage quality assurance team performs visual inspections, dielectric strength, continuity, operational tests and polarity checks at the factory. The fault is repaired and retested if a test fails. After all tests are passed, information is documented, dated, and signed off. Images and inspection reports are kept on file. Any third-party inspections, when required, are performed by state approved agencies.

Types of Electrical Accessories

Interior Explosion Proof Outlet

When storing chemicals that give off flammable vapors, gases, or combustible dust particles, explosion proof outlets have several unique features to maximize safety while preventing explosions.

These outlets prevent explosions by separating the plug from hazardous fumes and gases before making a connection with the outlet. Its unique twisting feature locks and isolates the plug to create an airtight attachment between plug and outlet. This ensures that sparking will not occur when the outlet begins drawing electricity, regardless of any combustible or flammable compound present.

Features & Benefits

  • NEMA compliant
  • Rated at 125 or 250 volts and 20 amperes
  • Available in single or two gang dead end assembly

Exterior Non-Explosion Proof Outlet

Our non-explosion proof outlets provide a reliable, compliant solution when you need a power source on the exterior of your building. These exterior outlets can be non-explosion proof, even when the material being stored is flammable. A weatherproof shield covers the outlet to ensure the it is protected and will always perform, regardless of climate changes or precipitation.

Electrical Load Center with Transformer

U.S. Chemical Storage’s standard load centers create a centralized location for electric panels and breakers, providing protection for all load bearing circuits. All load centers can be connected to a microcontroller that will switch critical systems to emergency power in the event of a power outage.

All custom electrical accessories come pre-wired to the building’s main control panel. Standard load centers are UL-Listed, Single Phase, 3-Wire, 120/240 V 100 A Load Center (NEMA 30) with a circuit breaker. Rainproof and sleet/ice-resistant enclosures are intended for use outdoors. Explosion and non-explosion load centers are available.

Explosion Proof Load Centers

Use explosion proof load centers in locations that are hazardous due to flammable gases or vapors, combustible dust, easily ignitable fibers and debris. These circuit breakers protect appliances against over-current and short circuiting and have main ratings of 100 to 225 amps.

Non-Explosion Proof Load Centers

Use non-explosion proof load centers in chemical storage buildings that will not be used to store flammable, combustible, or ignitable chemicals. Outdoor and rainproof non-explosion proof load centers are available with main ratings between 60 to 225 amps and capable of housing up to 42 circuit breakers.

Emergency Electrical Shutdown

An optional break glass shutdown can be installed on an exterior wall of any chemical storage building for emergency shut down of all electrical equipment operating inside the building such as exhaust fans, fan driven A/C and heating systems and more.

Junction Box

U.S. Chemical Storage electrical junction boxes are mounted on the building’s exterior. Use to protect wiring from exposure to hazardous environments, as well as to prevent damage from tampering.

Features & Benefits

  • Available in multiple sizes
  • Explosion and non-explosion proof models available
  • Available in single or two gang dead end assembly

Non-Explosion Proof Switches

Our non-explosion proof switches are used for situations where dust, grit, oil, grime, or moisture could otherwise impede the function of the switch or render it useless. Switch enclosures are particle and water tight, as well as corrosion resistant.

Features & Benefits

  • Available for alarms, circulating fans, pilot lights, and more
  • UL Listed, CSA Approved
  • Made of stamped aluminum

Wall Mount Telephone

Wall mount telephones are ideal for clean-room environments. Our wall mount telephone is protected with a weatherproof NEMA 4X enclosure for superior protection. The phone features a full keypad with push buttons for user compatibility, two auto-dial buttons, auto answer, and a smooth front panel. (Wiring to be completed by others.)

Features & Benefits

  • Weather-resistant steel construction
  • Chemical & UV resistant coating
  • Can be manufactured to meet EPA, NFPA 30 and NFPA 1
  • Continuously welded, leak-tested sump
  • Walk-in or rack style available
  • 15-year structural warranty

Compliance & Approvals

At U.S. Chemical Storage we strive to give you the best solution for your operations. This building and its accompanying accessories can be engineered to meet the following approvals and certifications based upon your unique set of needs.

Frequently Asked Questions

First consult the Safety Data Sheet (SDS) to determine the type of chemical you’re storing and any storage requirements listed. There are two main classifications of buildings to consider: fire-rated and non-fire-rated steel buildings.

There are three main questions you should answer before engineering or design can begin on your building: what is to be stored, how much of it is being stored, and where is the location it will be stored? You will also need to consult with your local “Authority Having Jurisdiction” (AHJ) or local code expert to determine your area’s specific storage building requirements.

Our team at U.S. Chemical Storage has a wealth of knowledge, experience, and resources to help analyze your storage needs, but the final approval is made by the local AHJ, so you will need to ultimately ask them about your requirements early in the planning process.

The definition of a “sump” is a pit or reservoir providing containment for spilled liquids. U.S. Chemical Storage offers leak-proof spill containment sumps in each standard model. All our sumps are tested for leaks for a 24-hour period prior to finishing. The sump is then covered by a steel or fiberglass floor grating and can even be equipped with a resistant plastic sump liner to protect against corrosive chemical accidental spills. The size of the sump is dictated by code based on the volume of liquid being stored within the building.

Building size is determined by the amount of hazardous material you are planning to store, the need for occupancy or inspection around these materials, and must take into consideration the most efficient way of moving these materials into and out of your chemical storage building.

Location of the building can be either inside another building or outside to fit your needs. Fire Separation, which is the amount of fire rating required between two occupancies, or the separation distance between those two occupancies, is determined by the type of chemical or hazard being stored, and distances between buildings, egress pathways, or environmental features. To determine the required fire separation, it is best to consult with your local code authority. Inside another building or within 10 feet of another building, you’ll be required to have a 4-hour fire rating. If your hazmat storage building is located at distances 30 feet or greater your building may not be required to have a fire rating at all.
