2 What is Hazard Communication OSHA Hazard Communication Standard 29 CFR – “Right to Know” went into effect in November 1985The purpose of Haz-Com is to communicate hazards associated with the workplace to employees.Employees have a Right to Know about the hazards in their work area and the potential effects of these hazards upon health and safety
3 Material Safety Data Sheets Hazardous Communications
4 MSDS Sections: Identification of chemical Hazardous Ingredients Physical DataFire and Explosion DataHealth Hazard DataReactivity DataPersonal Protection EquipmentSpill & Leak ProceduresHandling & Storage
5 Information included in MSDS sections Permissible Exposure Limits (PEL), Threshold Limit Value (TLV), other exposure limitsWhether a chemical in a carcinogenPrecautions to take for safe handling/useRecommended engineering controls.Emergency first aid proceduresDate of preparationName, address, phone number of manufacturer, importer, responsible party
6 MSDS RequirementsMohave Community College must have a MSDS for every hazardous substance an employee uses as part of the job.MSDSs must be available to an employee the entire time they are in the workplace.
7 MSDS RequirementsIf an employee requests a copy of an MSDS for a product he/she uses, and MCC cannot provide it after one working day, the employee may refuse to use that product or work in an area where the product is being used.If an employee requests a personal copy of an MSDS, MCC has 15 days to provide it.
8 Labeling & Marking Systems Hazardous Communications
9 Labeling & Marking Systems The OSHA Hazard Communication Standard requires that ALL hazardous materials be labeled. Labels must appear either on the container itself, the batch ticket, placard or the process sheets.Hazardous chemicals in portable containers which are for the immediate use of the employee who performs the transfer is the exception to this rule.
10 Labeling and Marking Systems Labels warn of potential dangersLabels are not intended to be the sole source of informationLabels serve as an immediate warningTypes of LabelsNFPA DiamondsHMIS LabelsUniform Laboratory Hazard Signage System
11 NFPA Diamonds Color coded, numerical system Will be located near main entrances, fire alarm panels, or on outside entrance doorsProvides at-a-glance hazard information
12 NFPA Diamonds Blue = Health Red = Flammability Yellow = Instability White = Special hazard information
14 HMIS LabelDesigned to go on individual containers of products that don’t have the manufacturer’s labelsSame color code/ numerical rating system as the NFPA diamonds
15 HMIS Label Blue = Health Red = Flammability Yellow = Instability White = Personal protective equipment or special protection informationNumerical Rating of 0- 4
16 Uniform Laboratory Signage Located on laboratory and chemical storage area doorsPictographs depict worst hazards present in lab or area
17 Remember!You should never have any unattended, unlabeled containers in your workplace!Always check with the appropriate personnel (lab manager, etc) before performing any work on maintenance in a laboratory!
19 Health Hazards include… Any chemical that may be harmful to your health is called a health hazard. Health hazards include:Corrosives – cause tissue damage and burns on contact with skin and eyesPrimary Irritants – cause intense redness or swelling of the skin or eyes on contact, but with no permanent damageSensitizers – cause an allergic skin or lung reaction
20 Health Hazards include… Acutely Toxic Materials – cause an adverse effect even at a very low doseCarcinogens – may cause cancerTeratogens – may cause birth defectsOrgan Specific Hazards – may cause damage to specific organ systems, such as the blood, liver, lungs, or reproductive system
21 Routes of Exposure Absorption – skin & eyes Ingestion – direct & indirectInhalationInjection
27 Protective MeasuresEngineering Controls – well designed work areas minimize exposure to materials which are hazardous (ie exhaust systems and wetting systems to control dust)Work Practices – Safe work practices will insure that chemicals are used correctly and safelyProduct Substitution – Because many chemicals do similar jobs, it is important to select chemicals that do a good job, while being less toxicPersonal Protective Equipment – Respirators, eye protection, gloves, aprons, and other protective equipment and clothing are designed to protect employees while working – USE THEM!
29 What now?Know the location and availability of hazard communication program, chemical and physical hazard inventory and MSDS files.Know what protective measures (PPE) you will need when dealing with hazardsSpeak with your supervisor about chemical specific and site specific Haz-Com training
30 What now?Knowing how to work safely with chemicals and other physical hazards is an important activity. This is the reason for the online training, site specific training, materials inventory and MSDSYou have a right to know, but you also have a responsibility to use the knowledge and skills to work safely!
