Chemical Hazards
Controlling Exposure
Hazard Control Methods• Engineering Controls
– Ventilation, enclosing operations, closed containers, replacement• Administrative Controls
– Training, information, limiting exposure time, policy/procedures• Personal Protective Equipment (PPE)
– Safety goggles, gloves, protective clothing
ENGINEERING CONTROLS
Best Practices• Dispense products in accordance with the label, safety
data sheet, and other product information• Use “closed” feed systems where possible • Store products in original container when possible• Store incompatible materials separately• Keep product containers closed when not in use• Mix products only in accordance with product
instructions• Use flammable and volatile chemicals only in well
ventilation areas
ADMINISTRATIVE CONTROLS
Best Practices• Read and follow label and safety data sheet
warnings and instructions• Post information regarding your hazard
communication process and chemicals• Properly plan your work to limit chemical
exposure time.• Inspect containers and feed systems before use• Wash hands and face after handling chemicals
• Know the location of emergency equipment (eyewash, showers, etc.)
• Follow SDS regarding personal protective equipment
• Use goggles and face shields when splash hazards are present
• Use gloves appropriate for the hazard (check SDS)
• Gas Monitors
PROTECTIVE EQUIPMENT
Best Practices
Emergency ActionsIf exposure occurs:• Eye Contact
– Flush for 15 minutes– Seek medical attention
• Inhalation– Move to fresh air– Seek medical attention
• Ingestion– Seek medical attention– Consult SDS
• Skin Contact– Remove contaminated clothing– Rinse skin for a minimum of 15 minutes

• Basics of Chemical Hazard Communication• Responsibilities• Chemical Hazard Concepts• Container Labeling• Safety Data Sheets• Controlling Exposure
What is Hazard Communication?
• Hazard Communication is a process that helps you understand and control the hazards of chemicals in your work environment.
• You have a legal “Right-to-Know” about the hazards of the chemicals you work with.
• Regulations establishing this have been in place for decades.

Health Hazards – Key Terms
20
Hazard Description
Corrosives Substances that can cause irreversible damage to the eye, skin or respiratory system.
IrritantCan cause a reversible inflammatory effect on eyes, skin and respiratory system.
Sensitizers Induces an allergic reaction / response to the respiratory system or skin – often upon repeat contact.
Toxic Capable of causing serious injury or death dependent upon exposure dose.
Carcinogen Can induce cancer or increase its incidence.
Mutagen Can cause change to genetic material in cells.
Reproductive Toxin
Can cause adverse effects to sexual function, fertility or development of offspring.
Pesticides Substances intended for preventing, destroying, repelling, or mitigating any pest. Biocides are a subset.
Physical Hazards – Key Terms
21
Hazard Description
FlammableLiquid with a flash point < 140oF. Flash point is the temperature at which a liquid gives off enough vapor to ignite in the presence of an ignition source.
CombustibleLiquid with a flashpoint >140oF and <200oF.
Oxidizer Material that can yield oxygen, thereby contributing to the combustion of other materials.
ReactiveMaterial (liquid, solid or gas) that is thermally unstable and can undergo violent reaction by itself or in combination with other materials (e.g. water reactive).
Organic PeroxideSpecial designation of reactive chemicals which may undergo exothermic decomposition. May burn rapidly, be sensitive to shock or friction, or react with other substances.
Others Flammable solids / gases, explosives, gases under pressure, self-heating chemicals

Upcoming Changes
• Globally Harmonized System for Classification and Labeling of Chemicals - GHS
• United Nations (UN) international mandate to standardize classification, labeling, safety data sheets and hazard symbols
• Being implemented around the world– Varying schedules– US – 2012 to 2015– Canada - TBD
New GHS Label Elements• New Signal Words
– “Warning” – less severe hazard– “Danger” – more severe hazard
• Standardized Hazard Statements– Examples – “Highly flammable liquid and vapor”, “Causes skin
irritation”• Standardized Precautionary Statements
– Examples – “Wear protective gloves”, “Do not breathe vapors”• Pictograms
Pictograms – Fire Hazards • Flammable• Pyrophoric• Self-Heating• Emits Flammable Gas• Self-Reactive• Organic Peroxide
• Oxidizer
Flame
Flame Over Circle

34
The Environmental Pictogram is non-mandatory for products sold in the United States.
The common name of the product, along with any other identifiers (e.g. product number) must be prominently displayed.
36
The name, address and telephone number of the manufacturer, importer or other responsible party must be listed.
37
The GHS pictograms for the product are also displayed. In this example, “Health” and “Fire” hazards.
38
The appropriate Signal Word is listed. Remember, “Danger” indicates a higher degree of hazard than “Warning”.
39
The appropriate Hazard Statements are given. In this case, representing the degree of flammability and the target organ potentially impacted (toxicity).
40
Precautionary Statements related to the Health and Fire hazards are displayed. Note there are statements related to Prevention, Response, Storage and Disposal. These statements are largely standardized by regulation, with the manufacturer adding additional information.
41
Additional, non-mandatory information can be added by the product manufacturer. May not conflict with or contradict other hazard information
42
Going Forward
In-House, HMIS, and NFPA labels will become less prominent as manufacturers move to the GHS labeling system through 2015. DOT and pesticide labels will remain until additional regulations are promulgated.
Safety Data Sheets
General Requirements• Must be available for each
hazardous chemical used• Must be in English but can
also be made available in other languages
• GHS requires a 16 section standardized format. Previously, manufacturers could choose the format.
• GHS-compliant SDS must be in place no later than 2015.

Section 2 describes the product hazard and includes many of the same elements as the label – Signal Words, Pictograms, Hazard Statements, and Precautionary Statements.
48
Our SDS describes hazards both “As Sold” and “At Use Dilution”. “Use Dilution” hazard are more representative of the product as used by the customer. Most chemical manufacturers do not provide this.
50
Section 7 includes details for proper storage and handling practices.
Section 8 outlines needed exposure control measures, including necessary personal protective equipment.
Obtaining SDS
• Ecolab / PureForce product SDS available through www.ecolab.com
• Customers must have a system for making SDS available to all product users at their facilities
Product Disposal Guidelines
• You are responsible for product disposal• Products may be classified as hazardous waste
due to characteristics such as corrositivity or flammability
• Only a licensed hazardous waste disposal company
• Never pour product into a drain unless the SDS indicates it is safe to do so
