HAZARDOUS WASTE PROGRAM FOR ROWAN UNIVERSITY LABORATORIES
- These detailed regulations define the legal and technical requirements for the disposal of hazardous wastes. In some instances the NJ Regulations are stricter than those of the Federal Environmental Protection Agency.
- Hazardous waste must be disposed of legally and safely. One can no longer pour hazardous materials or wastes down a drain or simply throw them in a dumpster. To do so is not only a violation of the law that could subject an individual or the University to heavy penalties, but is morally unconscionable.
- Detailed technical procedures on how to dispose of hazardous materials or wastes are outlined in the references at the end of this document.
- Additional information on a case-by-case basis can be obtained from Safety & EMS.
BASIC SAFETY INFORMATION
Safety is basically common sense; however, there are three safety rules which are violated with great regularity in laboratories, but which must be observed:
- Never work alone in a laboratory facility. If it is not possible to have two people in the same laboratory, ensure someone else is in close proximity (e.g., the same floor, or an adjacent room).
- No smoking, eating, or drinking is permitted in laboratories. Toxic material entry routes include inhalation and ingestion. Fire prevention safety prohibits smoking in high hazard areas, such as laboratories.
- Properly grounded electrical equipment or that especially designed for use in laboratories must be used. Home type equipment, e.g., refrigerators are not explosion proof and approved for laboratory use.
- Laboratory workers need to pay special attention to their personal grooming and jewelry items. Long hair must be restrained to prevent its coming in contact with hazardous materials or operations. Watches and rings should not be worn since they could react with hazardous chemicals or materials or get caught in equipment.
PERSONAL PROTECTIVE EQUIPMENT
- The correct use of personal protective equipment (PPE) can help reduce or minimize injuries to individuals working with hazardous materials or wastes. This apparel is intended to protect normal street clothing or skin from contact with hazardous materials.
- There are several types of protective apparel normally included within the term PPE. Some examples are eye, hand, body, foot, and respiratory protection. The use of any PPE must be very carefully matched against any of the materials involved and the degree of protection required. For example, almost all protective apparel can develop static electricity, so that if an individual does not ground, or bond himself or herself, there is a great danger that a static discharge might ignite volatile materials. In addition, protective apparel has time limits on the amount of time it can resist hazardous materials.
- Individuals wearing protective apparel needs to be mindful of those limits for the apparel and the type of hazardous material to which he/she is being exposed; therefore, it is important to be familiar with the proper selection and use of PPE prior to starting work.
- All PPE must be inspected before each use, and it is the responsibility of the individual wearer to accomplish this. A Pre-use inspection should include: looking for tears, punctures, discoloration, or brittle spots, which could indicate a defective condition. Defective PPE must not be worn or used. Laboratory workers should know the appropriate techniques for donning (putting on) and doffing (removing) contaminated protective clothing in an emergency.
- Examples of Personal Protective Equipment and Its Use
- Eye Protection:Eye protection is required for everyone (employees, students and visitors) in any location where chemicals are stored or handled. Protective eyewear is designed to keep material out of the eyes, or off of the face.
- Safety Glasses:Safety glasses must be made in accordance with the Standard for Occupational and Educational Eye and Face Protection (ANSI Z87. 1), from the American National Standards Institute. These requirements include: a minimum lens thickness of 3mm, impact resistance standards to be met, passage of a flammability test, and lens retaining frames. These can be prescription or non-prescription. Side shields may be attached to safety glasses that do not have built-in shields; however, side shields offer only limited protection for objects or materials approaching from the side of the wearer, and do not offer adequate protection against splashes or mists/vapors
- Goggles and Face Shields:
- Goggles are required for handling chemicals and hazardous materials within the confines of the facility. They are intended for use when there is danger of splashing chemicals, flying particles, or vapors/mists. Only "chemical style" goggles will be approved for use in the facility.
- Face shields offer some protection to the face and neck. Full-face shields should always be worn when maximum protection from harmful materials, especially liquids or particles, is needed. Safety glasses or goggles should be worn under the shield.
- Other Protective Clothing
The PPE Ensemble includes gloves, lab coats or aprons; coveralls or full body suits, and protective footwear constructed of fabric, or special materials such as butyl rubber or Tyvek.
- Gloves must be worn whenever it is necessary to handle rough or sharp objects, hot or cold materials, or whenever protection is needed against exposure to chemicals. Skin contact is a potential source of exposure to toxic materials. Gloves should not be worn around moving equipment or where they could become entangled and damaged.
- Lab coats are intended to prevent contact with dirt and minor chemical splashes or spills encountered in laboratory scale work. Lab coats, depending upon the materials they are made from, do not significantly resist penetration by organic liquids, and if contaminated, should be removed immediately.
- Aprons of plastic or rubber generally provide better protection for corrosive or irritating liquids, but can complicate injuries in the event a wearer is involved in a fire.
- Coveralls or full body suits, especially disposal ones, are generally preferred in high-risk situations. Generally, any coverall will have limitations as to the degree of protection offered and must be matched against the type of operation being performed and the materials involved.
- Foot protection such as rubber boots or plastic shoe covers may be required to avoid possible exposure to corrosive chemicals or solvents; however, shoe covers can increase the possibility of falling since they generally do not exert a great deal of friction on walking surfaces.
- Sandals or open toed shoes are prohibited in laboratories
- Respiratory Protection
- The primary method for protection of laboratory personnel from airborne contaminates is by engineered ventilation (e.g. fume hoods, exhaust systems). However, there are circumstances when these systems are not available, or increased personal protection is required. Should this be the case, suitable respiratory protection must be provided and used.
- Under Public Employee's Occupational Safety and Health Adoption of the Federal OSHA Standards (29CFR 1910), only equipment listed and approved by the Mine Safety and Health Administration (MSHA) and National Institute for Occupational Safety and Health (NIOSH) may be used. In addition, a respirator program must be in place within the institution.
- This program requires written information on the limitations, fitting methods, inspection and cleaning for each type of respirator that is used at the institution. The program begins with a physical examination prior to an individual being entered into a program that requires use of a respirator [Federal OSHA 29 CFR 1910.134 (b) (10)]. Specific training and fit testing of a respirator to each individual is also required
- Non-Emergency Respiratory Protection
- There are several types of non-emergency respirators available for protection in atmospheres that are not immediately dangerous to life or health (IDLH), but could be detrimental to an individual after prolonged or repeated exposure to a toxic atmosphere or substance.
- These respirators must be used only in atmospheres where the oxygen level is within normal range (19.5% approximately). Generally, use of a respirator will require the use of some other PPE (e.g., protective coveralls and gloves to protect skin from splashes of corrosives or materials that can be absorbed through the skin). Some types of common respirators are outlined below:
- Chemical Cartridge Air Purifying Respirators (APR) are designed for protection only against a particular individual or class of vapors or gases as specified on the cartridge. These units work by absorbing or filtering the contaminants out of the air. Activated charcoal is probably the most common type of absorbent. Because breakdown of the material of which the respirator is constructed is possible, it is important that the user know the type of hazardous material they are working with and any odors associated with the material. These respirators can be of complete or half-face coverage.
- Dust, Fume and Mist Respirators:
- These can be used only for limited protection against a particular class of dusts, fumes and mists; as specified by the manufacturer. These respirators trap toxic materials in a filter of fiber material. These are disposable units which are discarded when you can no longer easily breathe through them.
- Mask type respirators, such as surgical masks," are of little value and offer unsatisfactory protection in a laboratory environment. These types of respirators will not be used in Rowan laboratories.
- All respirators have certain drawbacks. For example, difficulty in breathing when the filter becomes clogged (a sign the filters must be changed), or over breathing. Over breathing occurs when the face piece collapses against the wearer's face because of insufficient airflow through the filters. This results from an improperly fitted face piece.
- An improperly fitted face piece will allow contaminated air into the wearer's respiratory system.
- Emergency Respirators:
- Self-Contained Breathing Apparatus (SCBA) are for trained emergency response personnel and are not available to employees, students, or guests. These devices consist of: An air supply cylinder, generally 5-30 minutes, a harness assembly to strap the unit on the wearer's back, and a regulator, which is hooked to the air supply cylinder.
- A protective ensemble is always required when wearing a self-contained breathing apparatus.
GENERAL SAFETY EQUIPMENT
A. All laboratories or storerooms in which chemicals are used should have certain routine safety equipment available; for example, safety showers, eye wash stations, first aid kits, lab sinks, fume hoods, and portable shields are required. Each laboratory worker (employee or student) needs to know the location of and proper use of each piece of safety equipment in the lab and should inspect each piece of equipment daily to ensure it will perform properly.
- Safety Showers must be tested periodically.
- Eye wash units must be capable of providing a soft stream or spray of water at no greater than 30 psig for an extended period (15-30 minutes). Insure that access to safety showers and eyewashes is not blocked or obstructed.
- First Aid Kits are required to be on hand in each laboratory for the prompt treatment of accidental injuries.
- Fume hoods are designed to remove noxious fumes from the work area. These hoods need to be inspected daily and before each use to insure the fans are operating. They should be tested at least semiannually to ensure that the design criteria are still met (e.g., to deliver 100 cfm of air across the face of the hood). A hood that is not operating cannot be used. Of course, fume hoods are not approved storage locations for hazardous materials; however, apparatus may be kept erected within a hood.
- Portable safety shields should be used whenever spattering, spraying, or explosion of chemicals or apparatus may occur.
- Vacuum distillation or other pressure related operations require the use of a portable shield.
EMERGENCY EQUIPMENT AND INFORMATION
A. Typical safety and emergency equipment in laboratories and related facilities are: portable fire extinguishers, automatic suppression or extinguishing systems, fire hose, fire blankets, and spill control equipment.
- All fire extinguishers have certain things in common. Each fire extinguisher has:
- A container with an extinguishing agent inside.
- A means of activation with a safety pin, seal and shutoff device.
- A discharge nozzle or hose.
- An instruction or identification plate, and label which tells the fire extinguisher classification and instructions for use.
- Class A fire extinguishers are used only on class A fires. On the Rowan campus these are 2 1/2 gallon water extinguishers.
- Class B and C fire extinguishers are a combination unit. These can be Carbon Dioxide, Dry Chemical (baking soda or potassium soda), or Halon 1211 agent.
- Class D fire extinguishers are filled with a special powder or highly refined sand. These cannot be used on any other class of fire.
- Multi-Class A,B,C, fire extinguishers are filled with a multi-purpose dry chemical powder and can be use on any of these classes of fire.
- Note: Bosshart Hall
- In Bosshart Hall, the portable fire extinguishers mounted in the hallways are Class A (the large chrome containers), and Multi-class ABC (the smaller red containers). Extinguishers must be inspected monthly by the building staff and the inspection tag dated and initialed on the back. The Safety Office will arrange for annual inspection of all portable extinguishers. Each laboratory user should inspect the fire extinguisher in their laboratory prior to each use of the lab, to insure it is serviceable. If the safety pin has been pulled, if the safety seal destroyed, if the gauge shows that the operating pressure is under or over limits, if there is some obvious defect, or if an extinguisher is missing, contact the Safety & EMS section for a replacement.
- Automatic fire suppression systems: Bosshart Hall's volatile storage room on the ground floor has a Halon 1301 system. Staff members concerned with working within that room will receive special instructions on the capabilities and use of this system.
- Fire Hoses: The University is no longer required to keep fire hoses on the campus.
- Fire Blankets: Many laboratories still have "fire blankets." These are now used only for first aid for shock, not for fire suppression or extinguishing of a person whose clothing is on fire. A person who has their clothes on fire should stop, drop and roll on the floor or ground, or use a safety shower if available, to extinguish the fire.
