12 Classifying Hazardous Materials The highlighted topics will be addressed in this module. Module 2 Classifying the Hazardous Materials 2012 IFC and IBC Hazardous Materials Provisions IFC and IBC Hazardous Materials Provisions Workbook page What is a Hazardous Material? IBC Section 202 and IFC Section 202 define a hazardous material as: - Those chemicals or substances which are physical hazards or health hazards as defined and classified in this chapter, whether the materials are in usable or waste condition. What is a Hazardous Material? Physical state of hazardous materials: -Solids -Liquids -Gases 2012 IFC and IBC Hazardous Materials Provisions Workbook page IFC and IBC Hazardous Materials Provisions Workbook page Copyright 2014 International Code Council #14312H12 12

13 Physical Hazard Hazardous Materials IBC Section 202 and IFC Section 202 define a physical hazard hazardous material as: - A chemical for which there is evidence that it is a combustible liquid, cryogenic fluid, explosive, flammable (solid, liquid or gas), organic peroxide (solid or liquid), oxidizer (solid or liquid), oxidizing gas, pyrophoric (solid, liquid or gas), unstable (reactive) material (solid, liquid or gas) or water-reactive material (solid or liquid). Physical Hazard Hazardous Materials It is important that the relative hazard of each class of physical hazard materials be reviewed: Explosives and Blasting Agents: Detonation or Deflagration; Burn Flammable and Combustible Liquids: Burn; Deflagration Flammable Solids and Gases: Burn; Deflagration Organic Peroxides: Burn; Deflagration Oxidizers: Accelerate burning Pyrophoric: Burn; Deflagration Unstable (Reactive): Burn; Deflagration Water Reactive: Burn; Deflagration Cryogenic Fluids and Compressed Gases: Burn; Deflagration in addition to stored potential energy IFC and IBC Hazardous Materials Provisions Workbook page IFC and IBC Hazardous Materials Provisions Workbook page Physical Hazard Hazardous Materials Hazardous materials are assigned numerical designations based upon their hazard potential. Health Hazard Hazardous Materials IBC Section 202 and IFC Section 202 define a health hazard hazardous material as: - A classification of a chemical for which there is statistically significant evidence that acute or chronic health effects are capable of occurring in exposed persons. The term health hazard includes chemicals that are toxic, highly toxic and corrosive IFC and IBC Hazardous Materials Provisions Workbook page IFC and IBC Hazardous Materials Provisions Workbook page Copyright 2014 International Code Council #14312H12 13

14 Health Hazard Hazardous Materials Health Hazard Hazardous Materials The classification of materials as either toxic or highly toxic is determined by the: -Lethal dose to 50 percent of a group of test animals (LD 50 ). -Lethal concentration to 50 percent of a group of test animals (LC 50 ). Corrosive materials cause damage to human tissue that results in visible destruction or irreversible alterations based on a single 4-hour exposure. - The definition in the I-codes is based on the US Department of Transportation classification for corrosive materials IFC and IBC Hazardous Materials Provisions Workbook page IFC and IBC Hazardous Materials Provisions Workbook page Evaluation of Health Hazard Mixtures Lethal concentration and dose values published in scientific sources and journals are based on pure chemicals or mixtures. IFC Section requires mixtures to be classified as a whole. The amount of material that is either highly toxic or toxic can influence the material s classification. Evaluation of Health Hazard Mixtures For materials with lethal concentration values, the proper classification criteria are found in 2012 IFC Appendix E, Section E , which references Compressed Gas Association Standard P-20, Standard for Classification of Toxic Mixtures IFC and IBC Hazardous Materials Provisions Workbook page IFC and IBC Hazardous Materials Provisions Workbook page Copyright 2014 International Code Council #14312H12 14

15 Classification Assistance IBC Section and IFC Section requires that sufficient information be provided to the code official to issue either construction or operational permits.

16 Situation of the Hazardous Materials Before the MAQ can be determined, its situation must be evaluated and assigned. The situation of a hazardous material can be either: -Storage; -Use-closed; or -Use-open. Storage and Use Defined IBC Section 202 and IFC Section 202 defines storage, hazardous materials as: - The keeping, retention or leaving of hazardous materials in closed containers, tanks, cylinders, or similar vessels; or vessels supplying operations through closed connections to the vessel IFC and IBC Hazardous Materials Provisions Workbook page IFC and IBC Hazardous Materials Provisions Workbook page Storage and Use Defined Closed-Use System A closed-use system is defined in IBC Section 202 and IFC Section 202 as: - The use of a solid or liquid hazardous material involving a closed vessel or system that remains closed during normal operations where vapors emitted by the product are not liberated outside of the vessel or system and the product is not exposed to the atmosphere during normal operations; and all uses of compressed gases IFC and IBC Hazardous Materials Provisions Workbook page IFC and IBC Hazardous Materials Provisions Workbook page Copyright 2014 International Code Council #14312H12 16

17 Closed-Use System Open-Use System IBC Section 202 and IFC Section 202 defines an open-use system as: - The use of a solid or liquid hazardous material involving a vessel or system that is continuously open to the atmosphere during normal operations and where vapors are liberated, or the product is exposed to the atmosphere during normal operations. Examples of open systems for solids and liquids include dispensing from or into open beakers or containers, dip tank and plating tank operations IFC and IBC Hazardous Materials Provisions Workbook page IFC and IBC Hazardous Materials Provisions Workbook page Open-Use System Module 4 Determining the MAQ for Each Hazardous Material 2012 IFC and IBC Hazardous Materials Provisions Workbook page Workbook page Copyright 2014 International Code Council #14312H12 17

18 Determining the MAQ for Each Hazardous Material The highlighted topics will be addressed in this module. Determining the Maximum Allowable Quantity of Hazardous Materials After determining the physical state, situation and classification of the hazardous material, the MAQ can be determined IFC and IBC Hazardous Materials Provisions Workbook page IFC and IBC Hazardous Materials Provisions Workbook page Determining the Maximum Allowable Quantity of Hazardous Materials IBC Section 202 and IFC Section 202 defines the MAQ as: - The maximum amount of a hazardous material allowed to be stored or used within a control area inside a building or an outdoor control area. The maximum allowable quantity per control area is based on the material state (solid, liquid or gas) and the material storage or use conditions. Determining the Maximum Allowable Quantity of Hazardous Materials The Maximum Allowable Quantity values for indoor storage and use are located in: IBC Table 307.1(1) and IFC Table (1) for physical hazard hazardous materials. IBC Table 307.1(2) and IFC Table (2) for health hazard hazardous materials. Outdoor control area MAQ are located in IFC Tables (3) and (4) IFC and IBC Hazardous Materials Provisions Workbook page IFC and IBC Hazardous Materials Provisions Workbook page Copyright 2014 International Code Council #14312H12 18

Permissible MAQ Increases Note e states: Maximum allowable quantities shall be increased 100 percent when stored in approved storage cabinets, day boxes, gas cabinets, exhausted enclosures, or listed safety cans. Listed safety cans shall be in accordance with IFC Section Where Note d also applies, the increase for both notes shall be applied accumulatively IFC and IBC Hazardous Materials Provisions Workbook page IFC and IBC Hazardous Materials Provisions Workbook page Copyright 2014 International Code Council #14312H12 19

20 Permissible MAQ Increases A similar note f is included in IBC Table 307.1(2) and IFC Table (2) for health hazard materials which permits a 100 percent increase for approved storage cabinets, gas cabinets or exhausted enclosures. Permissible MAQ Increases Note d in IBC Table 307.1(1) and IFC Table (1) for physical hazard materials states: - Maximum allowable quantities shall be increased 100 percent in buildings equipped throughout with an approved automatic sprinkler system in accordance with Section Where Note e also applies, the increase for both notes shall be applied accumulatively IFC and IBC Hazardous Materials Provisions Workbook page IFC and IBC Hazardous Materials Provisions Workbook page Permissible MAQ Increases A combination of these two notes for an approved sprinkler system and approved storage protection where permitted allows for a substantial increase in the MAQ permitted in one control area without warranting a Group H occupancy classification. Ethane Storage MAQ Example Given: A business stores and uses ethane for its manufacturing process. The one-story building is protected throughout by an automatic sprinkler system and the cylinders are stored in ventilated gas cabinets. Q. What is the MAQ if the building is considered as a single control area? 2012 IFC and IBC Hazardous Materials Provisions Workbook page IFC and IBC Hazardous Materials Provisions Workbook page Copyright 2014 International Code Council #14312H12 20

21 Ethane Storage MAQ Example 1. Ethane is classified as a compressed flammable gas. 2. The MAQ for storage and the closed use of compressed flammable gases is 1,000 ft NTP in accordance with IBC Table 307.1(1) and IFC Table (1). Ethane Storage MAQ Example 3. IBC Table 307.1(1) and IFC Table (1) Note d permits a 100 percent increase in the MAQ when the building is protected by an automatic sprinkler system. (100%)(1,000 ft 3 ) + (1,000 ft3) = 2,000 ft 3 4. Note e of the same tables permit an additive 100 percent increase when storage is in an approved gas cabinet. (100%)(1,000 ft 3 ) + (1,000 ft 3 ) = 2,000 ft 3 plus the 2,000 ft 3 for sprinkler protection for a total MAQ of 4,000 ft IFC and IBC Hazardous Materials Provisions Workbook page IFC and IBC Hazardous Materials Provisions Workbook page Ethane Storage MAQ Example When both notes d and e of IBC Table 307.1(1) or IFC Table (1) are applicable, the permitted tabular MAQ can be increased by a factor of 4 without warranting a Group H occupancy classification. The MAQ Activity Purpose: To apply the knowledge of determining the MAQ per control area.
