I. SCOPE
If your business uses, stores or handles hazardous materials in quantities exceeding the Permit Level Amounts
(page 10) as stated in the International Fire Code (IFC) with Denver Amendments (IFC Section 2701.5.2), you are
required to fill out a Hazardous Materials Inventory Statement (HMIS) and to obtain a Hazardous Materials Permit.
The permit constitutes permission to maintain, store, use or handle materials, or to conduct processes that produce
conditions hazardous to life or property, or to install equipment used in connection with such activities.
II. ANNUAL PERMIT REQUIREMENTS
The Denver Fire Department, Fire Prevention & Investigation Division will issue the annual Hazardous Materials
Permit. For new and existing facilities that store or use hazardous materials, an HMIS is required by the fire
department to evaluate applicant’s storage layout, methods of storage and use and commodities being stored for
compliance with all International Fire Code, International Building Code, and NFPA requirements. The HMIS
shall be completed by a qualified individual who is familiar with the requirements of the International Fire Code,
International Building Code, and applicable provisions of the National Fire Protection Association publications.
The fire code official is authorized to require HMIS submittals to be prepared by an authorized individual or firm.
These are the Four Required HMIS Forms:
(1) General Information Form – Sign the last page - Scanned copy allowed
(2) Chemical Inventory Report (the ACTUAL DFD Excel spreadsheet: Submit Annually)
(3) Hazardous Materials Management Plan (HMMP) - Scanned copy allowed
(4) Facility Graphic Maps - Scanned copies allowed
A permit may be suspended or revoked when it is determined that the permit was issued in error or in violation of
an ordinance, regulation or code. False statements or misrepresentations of information provided in the HMIS
submittal may result in a criminal complaint being issued for violation of Section 109.2.2.1 of the IFC Denver
Amendments.

IV. INSTRUCTIONS for COMPLETING the HMIS
(1) GENERAL INFORMATION FORM
Complete the General Information Form. Save file as: ‘your street address, date’ (i.e. 123 Main Street, 012010) in Microsoft Word. Provide an electronic signature or scan a signed copy.
(2) CHEMICAL INVENTORY SPREADSHEET
The information needed to complete the Chemical Inventory Spreadsheet can be found on the Material Safety
Data Sheets (MSDS) and/or the product label for each product. Fill in the following fields: The product’s name,
CAS number, location code, both use and total amounts of each product, all NFPA 704 Ratings of the product,
and all corresponding IFC Hazard Categories that apply. Follow all instructions provided in the comment boxes,
red flagged on spreadsheet. Save file as: ‘your street address, date’ (i.e. 123 Main Street, 01-2010).
CHEMICAL INVENTORY REPORTING GUIDELINES:
 Mixtures shall be classified in accordance with hazards of the mixture as a whole.
 For mixtures which have more than one single CAS number, list all CAS numbers.
 Any product or chemical which meets or exceeds the permitable amounts in any IFC classification shall be
reported.
 Report the Maximum Quantity of products you would have on site at any given time.
 If the products or chemicals to be bulked are stored or used in different control areas in your facility, each
location will require a separate entry on the chemical inventory report.
 Products or chemicals that are in temporary locations (awaiting transport on shipping dock, etc.) shall be
reported from their primary or permanent location.
 Report separate entries for ‘Use’ and ‘Storage’.
 All products or chemicals will require an individual entry on the chemical inventory report spreadsheet.
Exceptions:
If products are:
1) stored or used in the same location,
2) have the same NFPA 704 hazard rating,
3) and are in containers not greater than 1 gallon or 10 pounds.
These may be reported as aggregates. For example: Paints having the same base, but different colors and
containers sizes up to 1 gallon may be bulked as one entry on the spreadsheet.
(3) HAZARDOUS MATERIALS MANAGEMENT PLAN (HMMP)
Any facility with a permit for hazardous materials shall develop a Facility Contingency Plan and provide a
narrative description of the operations and processes taking place at the facility. Inspectors will confirm that a
copy is on site. Save file as: ‘your street address, date’ (i.e. 123 Main Street, 01-2010) in Microsoft
Word. The Plan shall include the following:
General Facility Information: General information, including business name and address, emergency
contacts, business activity, business owner or operator, SIC code, number of employees and hours, Dunn and
Bradstreet number, and signature of owner, operator or designated representative.

VII. NFPA 704 Placarding
In all occupancies where hazardous materials are stored, dispensed, used or handled in quantities requiring a permit
the IFC requires visible hazard identification signs, as specified in NFPA 704. This standard provides a simple
system of readily recognizable and easily understood markings, which will give at a glance a general idea of the
inherent hazards of any material and the order of severity of these hazards as they relate to fire prevention, exposure
and control. This standard requires all buildings with chemical amounts exceeding the permit quantities to be
placarded. The placard for each building or area shall represent the collective extreme hazard rating for all products
in that building or area. The Denver Fire Department requires a minimum of two external placards mounted in
separate locations:
 One placard must be mounted on the front of the building in a permanent and stationary location,
with no visual barrier to the street.
 The second placard must be fixed near the secondary means of egress. If your facility is fenced,
this second placard may be placed on the vehicle entrance gate.
 Fences surrounding exterior storage areas and detached storage buildings must also be placarded.
 Internal placards are also required
 Position placards above doorways to rooms where hazardous materials are stored or used.
 In open, inside locations where hazardous materials are stored or used, mount the placards on the wall above
and behind the product; rack storage requires that placards be placed at both ends of the aisle.
All signage must comply with NFPA 704. All signs must have contrasting numbers and symbols. Exterior signs
shall be a minimum of 15" by 15"; interior signs shall be a minimum of 10” by 10”. In situations where a wide
variety of materials having varying degrees of hazards are stored, the identifying numerical values and symbols
shall indicate the most severe degree of hazard in each category. These placards are available from companies
listed in the phone book under “Fire Protection”. If you have any questions or concerns, please feel free to contact
the Fire Prevention Bureau, Hazardous Materials Division, during normal business hours at 720-913-8288.

damaging agents, reproductive toxins, cutaneous and eye hazards not classified as irritant or corrosive.
OTHER HEALTH HAZARD MATERIAL is a hazardous material which affects target organs of the body,
including, but not limited to, those materials which produce liver damage, kidney damage, damage to the nervous
system, act on the blood to decrease hemoglobin function, deprive the body tissue of oxygen, or affect reproductive
capabilities, including mutations (chromosomal damage) or teratogens (affect on fetuses).
