EMPLOYEE INFORMATION

The goals of the District’s chemical hygiene and safety training program are to ensure that all individuals at risk are adequately informed of:

• The physical and health hazards associated with chemicals. • The hazardous materials and waste present or generated in the laboratory. • The proper procedures to minimize risk of exposure. • The proper response to spills. • All school staff whose assigned work locations include a laboratory area

shall participate in an ongoing chemical hygiene and safety training program. This includes custodial and maintenance personnel.

7


EMPLOYEE TRAINING

• The scope of training an employee receives is determined by the scope of work assignment.

• Training for custodians would include procedures for performing necessary cleaning activities in the presence of laboratory chemicals.

• Training will be directed to classes or groups of hazardous chemicals, rather than to the specific characteristics of many individual chemicals.

• General content of the training and information program will include State Chemical Hygiene and Safety standards, including the contents of Section 5191 of the General Industry Safety Orders of Title 8, California Code of Regulations.

• Location and content of CHSP• Hazards of chemicals, PEL or other exposure limits, TLV, Lethal Dose(LD)50 and

routes of entry• Labeling and storage requirements• Chemical evaluation and authorization• Location and content of Safety Data Sheets for chemicals at the school site

EMPLOYEE TRAINING (CONT.)

• Location and proper use of available Personal Protective Equipment. • Signs and symptoms associated with an exposure to hazardous chemicals associated with

the laboratory • Methods to detect the presence or release of hazardous contaminants (e.g., air monitoring). • Proper response and reporting procedures for chemical releases/spills and evacuation. • The training program will be an ongoing process, consisting of an initial orientation for new

employees and annually to the science staff thereafter. The Chemical Safety Coordinator will document and maintain records of the ongoing training received by employees

• To assist science teachers, administrators, and other school staff members understand and avoid situations in which accidents might occur, the State of California has prepared the Science Safety Handbook for California Public Schools (*.pdf) CSCs are encouraged to download and review the handbook.

• Science Safety Handbook updates can be viewed in its entirety online. The following are the updates to the 2012 Edition of the Science Safety Handbook:

-Globally Harmonized System of Classification and Labeling of Chemicals (GHS)

-Revisions to the proper occupant load factor for science labs (from 20 square feet to 50)

-Addition of 2,4-Dinitrophenol to Tables 7.2 and 7.3

Globally Harmonized System (GHS) of Classification and Labeling of Chemicals is a worldwide initiative to promote standard criteria for classifying chemicals according to their health, physical and environmental hazards. It uses pictograms, hazard statements, and the signal words “Danger” and “Warning” to communicate hazard information on product labels and safety data sheets in a logical and comprehensive way. The primary goal of GHS is better protection of human health and the environment by providing chemical users and handlers with enhanced and consistent information on chemical hazards.


SAFETY DATA SHEETS (SDS)

• Safety Data Sheets (SDS) received for all laboratory chemicals should be kept in the Science Chemical Safety Data Sheets binder and be readily accessible to employees.

• SDS’s are available electronically on the OEHS website accessible through the LAUSD.net website.

• SDSs are required to be presented in a consistent 16-section format.

• Provide detailed health and safety information and precautions for handling, storing and transporting hazardous substances, including emergency and first aid procedures.

re-label items if the labels are removed or defaced.• Workplace labels can either provide all required information on the original chemical

manufacturer’s label or, the product identifier and words, pictures, symbols or a combination of these.

• If the employer is aware of newly-identified hazards that are not disclosed on the label, the employer must ensure that the workers are informed.

• Employers may continue to use rating systems such as National Fire Protection Association (NFPA) diamonds or HMIS requirements for workplace labels as long as they are consistent with the requirements of the Hazard Communication Standard and the employees have immediate access to the specific hazard.

27


LABELING AND DISPOSAL (CONT.)

Containers shall be labeled with the following information: • Used-chemical category • Name of chemical(s) in the container • Approximate percentage of each chemical (if mixed) • Date prepared • Name of teacher or room number

address of school, composition and physical state of the waste, and accumulation date.

• It is unlawful to store hazardous wastes at school sites for longer than 90 to arrange for the pickup of hazardous materials and/or wastes.

28


LABELING AND DISPOSAL (CONT.)

Chemical Waste Disposal

If used chemicals become reclassified as hazardous waste, their containers will

be relabeled as such and segregated into the following classes for disposal

(EPA categories): • Ignitable: Materials capable of causing fire. • Corrosive: Aqueous solutions with a pH less than or equal to 2 or greater

than or equal to 12.5. • Reactive: Substances that are unstable, explosive, water reactive, or

generate toxic gases. • Toxic: Substances that are harmful to human health such as arsenic,

barium, cadmium, chromium, lead, mercury, selenium, silver. • Other waste not falling into one of the above classes should be identified by

chemical names.

29


LABELING AND DISPOSAL(CONT.)

• Labels must be legible, in English, and prominently displayed. Other languages may be displayed in addition to English. Chemical manufacturers, importers, and distributors who become newly aware of any significant information regarding the hazards of a chemical must revise the label within six months.

• Each pictogram consists of a symbol on a white background framed within a red border and represents a distinct hazard(s). The pictogram on the label is determined by the chemical hazard classification.

30


DISPOSAL

• Disposal Procedures for Hazardous Waste and Universal Waste are outlined in REF-4149.00

• Universal wastes, such as fluorescent light tubes, batteries, and cathode ray tubes, are not allowed to be disposed of in regular trash effective February 8, 2006. At Schools Universal waste shall be collected in separate, properly sealed, DOT approved containers, each affixed with a “universal waste” label and stored in an area designated by the Plant Manager.

• To request disposal of universal waste from school sites, complete the Hazardous Waste Pick-up Request form and e-mail it to OEHS by clicking on the button labeled “Submit by e-mail.” If you do not have access to an LAUSD e-mail account, you may fax a copy of the old request form to OEHS at (213) 241-6816.

established Permissible Exposure Limit (PEL) or Threshold Limit Values (TLV), or exhibits signs or symptoms of such exposure, the employee shall have the opportunity to receive a medical consultation to determine the need for medical examination.

• Medical exams and consultations performed at a reasonable time and location without the cost to the employee.

• The physician will be provided with: identity of the chemical(s) to which the employee may have been exposed, exposure conditions; and employee's signs and symptoms of possible exposure.

• A record of consultation, tests performed and conclusions will be provided to the employee and school district. CalOSHA regulations require that records of air concentration monitoring, exposure assessments, medical consultations, and medical examinations be maintained for at least 30 years after the employee leaves school district employment.

38


CHEMICAL INVENTORY RECORDS

• An inventory of all chemicals stored in each school building shall be

conducted annually and chemical usage determined.

• Inventory information shall include the chemical name, quantity,

hazard information, and storage location.
