The completed Hazardous Materials submittal must be mailed or hand delivered to the Clark County Fire Department, Plans Check Division located at 575 E. Flamingo Rd, Las Vegas, NV 89119. Our hours of operation are between 8am and 4pm Monday thru Friday, excluding Holidays. There is a $75 minimum plan review fee, which is due upon submittal of the plans. Hazardous Materials submittals may be charged escalating fees after the plans are reviewed. Escalating fees are calculated by the quantities reported in your plan submittal. You can review our Permit Calculation Table and Fee Schedule by visiting our website at www.accessclarkcounty.com/fire. You must pay any additional fees before you receive your reviewed plans. It is important to note that once you have received your approved plans, you must schedule an inspection to finalize the permitting process. An inspector will conduct an on-site inspection and verify that the approved plans match the location set-up. If the inspection is approved, the permit will be signed and issued by the Inspector. Note: Your Hazardous Materials submittal must include three (3) copies of the following information: Fire Department Renewable Permit Application Form (provided) Operational Narrative Chemical Inventory Sheet Site Map - 1 -
CHEMICAL INVENTORY SHEET You should fill out the information on the chemical inventory sheet as thoroughly as possible. Each one of the fields is necessary information to ensure that the proper safety requirements are met. Chemical Name/Product Name Chemical name is the name that appears on the corresponding Material Safety Data Sheet (MSDS). The product name is the common name, or the name that appears on the packaging or container. Many chemicals have several different names associated with them. It is important that you use a name that appears on the MSDS as well as the product name so that the chemical can be matched to the appropriate MSDS and located in the field inspection. Chemical Classification - this is the classification that describes the hazards associated with the chemical. There are specific chemical hazards that are addressed individually by the 2005 Clark County Fire Code. It is important to know the hazard classification of each chemical in order to determine many different aspects of safely handling that chemical, such as permit amounts, exempt amounts, storage requirements, use requirements, fire safety system requirements, etc. In order to classify the chemicals used in your operation, you will need to consult the MSDS. Every hazard category has a specific definition that can be matched using the information provided on the MSDS. Some of the possible chemical classifications include: flammable and combustible liquids, oxidizers, explosives, corrosives, irritants, sensitizers, flammable solids, and more. Please group all like hazard categories and indicate the totals for each category on your inventory sheet. Physical State - this is the physical form of the chemical. Chemicals can either be solids, liquids, or gases at standard atmospheric temperature and pressure. NFPA 704 Hazard Ranking - these are the numbers that correspond to the level of possible threat of a chemical in three aspects. The numbers are represented in a four color diamond, in which each color represents a separate aspect. The health hazard (blue), fire hazard (red), reactivity hazard (yellow), and special hazard (white) give an emergency responder the information necessary to safely secure an incident scene. The health, fire, and reactivity categories are all represented by numbers from 0-4, with 0 representing the least hazard and 4 representing the most hazardous. The special hazard section will not have a number, but instead a word or symbol that denotes a hazard. For example: a W with a line drawn through it would represent a water reactive chemical; OXY would indicate an oxidizer; COR would represent a corrosive. Most MSDS will have listed the NFPA 704 hazard numbers associated with that specific product. They will usually be listed as: H-1 F-3 R-0 to represent the corresponding health, fire, and reactivity numbers. There is another hazard ranking system that uses a very similar number system called HMIS. The NFPA 704 hazard rankings and the HMIS hazard rankings are NOT the same and are not interchangeable. In an effort to save space on your inventory sheet, you can simply list the numbers in the box in the following order: Health, Fire, Reactivity, Special. If your MSDS does not contain the NFPA 704 hazard rankings, and you have already attempted to contact the manufacturer for the information, you can then leave this box empty. Inventory Amount - This number represents the highest amount of that chemical you may have on hand at any given time. This number DOES NOT represent the average amount of chemicals on hand. For the purposes of this permit, it is important to know how much of any chemical may be on hand, including fluctuations due to shipments, seasonal changes, use, or any other reason the amount might change. Please indicate the units of measurement for each chemical entry using standard abbreviation. If the chemical is in an aerosol can or other similar container, please be sure to indicate the size of each can as well as the total number of cans. Please use gallons, pounds, and cubic feet when stating quantities. Storage/Use Location - Include the grid number from the site map that indicates the storage and or use location of the chemical. If there are multiple storages and use locations, indicate all locations on the inventory sheet. - 2 -
Container type - This is the method in which the chemical is stored. Please indicate one of the methods of storage listed below using the letter associated with that container. Also indicate the size of each individual container in parenthesis next to the letter. Aboveground tank (60 gal. Or More) Below ground tank (60 gal. Or More) Tank inside building (60 gal. Or More) Steel Drum (55 gal. Or less) Plastic or non metal drum (55 gal. Or less) Can Carboy Silo Fiber drum Bag Box Cylinder Glass bottles or jugs Plastic bottles or jugs Tote bin Tank wagon Rail car Plastic bucket Metal bucket Cryogenic metal drawer Aerosol cans Other - 3 -

ORGANIC PEROXIDES Organic peroxide is an organic compound that contains the bivalent 0-0- structure and which may be considered to be a structural derivative of hydrogen peroxide where one or both of the hydrogen atoms have been replaced by an organic radical. Some organic peroxides can present an explosion hazard (detonation or deflagration) or they can be shock sensitive. Organic peroxides will decompose over time at a rate that increases with increasing temperature. Decomposition products may be flammable. Organic peroxides are subdivided into classes as follows: Detonatable: Detonatable organic peroxides are capable of detonation. These organic peroxides present an extremely high explosion hazard through rapid explosive decomposition and are regulated as explosives.
