The hazard identification section includes the hazard classification $($class$,$ category$)$ of the substance or mixture, or a description of the identified hazard for the "Physical$/$Health hazard not otherwise specified" class. This section also includes the following label elements: Pictogram or the name of the symbol $($like "Flame" or "Skull and crossbones"$)$ Signal word Hazard statements$)$ Precautionary statements$)$Section $2$ also includes other hazards which do notHazard$($s$)$ Identificationresult in classification, like a molten metal hazard.Section $4$ includes first aid measures by route of exposure: inhalation, dermal $($skin contact$),$ eye contact, or ingestion.This section includes the most important symptoms and effects$-$whether acute, chronic, cumulative, or mutagen. Section $4$ also includes advice on medical attention and special treatment, if necessary.This section dictates personal precautions, protective equipment, and emergency procedures in the event of a spill to mitigate the potential negative effects on you, others, and the environment. Section $6$ also includes methods and materials for containment and cleaning up$.$Section $7$ recommends appropriate precautions for the safe handling of hazardous materials and necessary conditions for safe storage, including a list of incompatible materials.Section $8$ contains control parameters, including occupational exposure guidelines or biological exposure limits and the source of those values, to reduce hazard potential. Appropriate engineering controls are also given.Individual protection measures required, such as PPE, are listed.Section $9$ provides a comprehensive list of all physical and chemical properties applicable to the hazardous material including: Appearance Initial boiling point$/$boiling range Odour Flash point $($the lowest$*$ Odour threshold $($the lowesttemperature at which a liquid givesairborne concentration of aoff enough vapour to ignite thatchemical that can be perceived by vapour if an ignition source is the sense of smell, normallyavailable$)$expressed as parts per million$)$ Evaporation rate pH $($a rating, from $0$ to $14,$ of how Flammability acidic or alkaline a product is; $0$ is the most acidic, $7$ is neutral, and numbers above indicate that it is alkaline$)$ Melting$/$freezing points Lower$/$upper flammable$/$explosive Coefficient of water$/$oil distribution limit $($the minimum$/$maximum air$($tells you if the product is likely toconcentration of a gas or vapourmix with grease and oil morethat can create an explosivequickly and the likelihood of skinsituation if an ignition source isabsorption; greater than $1$ means itavailable$)$mixes better with water and is Vapour pressure $($how able amore likely to be absorbed$)$substance is to form vapours; Auto$-$ignition temperature $($tellshigher pressures are moreyou when a gas or vapour willhazardous$)$automatically ignite in the absence Vapour density $($a measure of howof an ignition source$)$heavy or light a gas is compared to air; less than $1$ is lighter than air; high than $1$ is heavier than air$)$Section $10$ describes the reactivity and chemical stability of a hazardous material. Details include possible hazardous reactions, conditions to avoid such as static discharge, shock, or vibration$-$and incompatible materials.Hazardous decomposition products are also listed.StabilitySection $11$ features a concise but complete description of the various toxic health effects and the data used to identify those effects. It includes: Information on the likely routes of exposure $($inhalation$,$ ingestion, skin,and eye contact$)$ Symptoms related to the physical, chemical, and toxicologicalcharacteristics The delayed, immediate, and chronic effects from short$-$term and long$-$term exposure $($such as mutations, birth defects,organ damage, irritations, sensitivity$,$ and carcinogenicity$)$Toxicology information includes the numerical measures of toxicity, such as: The Lethal Dose $50($LD$50)-$ the dosage by a specific route of exposurewhich causes $50\%$ of animals to die The Lethal Concentration $50($LC$50)-$ the concentration of ingredients in the air at which $50\%$ of animals dieUnder WHMIS $2015,$ Section $12$ is optional. Only the heading is required on the SDS as the supplier can choose not to provide information in this section.When ecological information is present under Section $12,$ it includes aquatic and terrestrial toxicity levels. The persistence or degradability of the toxin is also discussed along with the bio$-$accumulative potential and environmental mobility$-$both of which are used to assess long$-$term effects on the environment. Section $12$ also mentions any other adverse effects on the environment.Which sections of an SDS tell you what the hazards are? $($Choose ALL that apply.$)$ Section $2$: Hazards Identification Section $4$: First Aid Measures Section $6$: Accidental Release Measures Section $7$: Handling and Storage Section $8$: Exposure Controls$/$Personal Protection Section $9$: Physical and Chemical PropertiesSection $10$: Stability and ReactivitySection $11$: Toxicological Information Section $12$: Ecological Information
