A Safer Workplace
The Department of Chemical Engineering at Texas Tech University is obligated to provide and promote a safe and secure work area. A safer office/laboratory presents a more productive work environment. With safety and security enforced, there are substantially less areas where injuries can occur. A minimized amount of injured personnel provides more time to focus on work and allows more productivity.
Everyone involved with the Department of Chemical Engineering at Texas Tech University is responsible for the safety and security of themselves and others who might enter the facilities. Duties will vary from department head to professor/researcher to student to guest, but the focus will maintain emphasis on safety.
In order to fulfill safety requirements, the rules under legislation and University policy must be followed. While in the laboratory, don the necessary personal protective equipment (PPE). Make sure all your employees have been trained on the hazards that they might face in their work environment. If an accident occurs, record the event, notify the proper authorities, and take action to prevent recurrence.

Chemical Engineering Safety & Security Committee
The CESSC serves as an advisory committee concerned with safety, health and environmental protection. From its meetings, recommendations are made for addressing hazards and improving safety. The safety committee should meet on a regular basis, although special sessions will be called if necessary.
Members of the CESSC consist of the safety officer and three department representatives. Members are appointed by the departmental chair. The committee shall meet a minimum of once per year and will distribute discussed information to the entire department. If needed, this safety plan will also be updated to include changes that might occur.
Environment Health and Safety at TTU, MS 1090, has the necessary forms for reporting accidents. These are:
- TWCC−IS − Employer’s first report of injury/illness −accident involving lost time or medical costs
- AGS−10−91/TWCC−121 − Supervisor’s Investigation of Employee’s Accident/Incident
- C−80 − Employee’s Election Regarding Utilization of Sick Leave
- WCD−29 − Employee’s Report of Injury
- 24−016−C − Authorization for Release of Information
- TWCC−6 − Supplemental Report of Injury/Illness
- WCD−74 − Witness Statement
- Incident Report Form goes to EH&S for incident and near−miss, no lost time and no lost medical cost injury
- Hazard Report Form goes to EH&S
Investigations are conducted at the discretion of TTU EH&S. If an investigation is deemed necessary, a EH&S team will be enacted and the chemical engineering department will work directly with that team.
Periodic Workplace Surveys
The Texas Tech University Department of Chemical Engineering safety coordinator and chair will accompany EH&S when they visit for their biannual workplace surveys. These visits may include measurements in noise and lighting, hazard communication program review, and a walk−through of facilities to determine potential hazards. Recommendations will then be presented for ways to reduce hazards in the Department of Chemical Engineering.
Hazard Communication Program
Under the Texas Hazard Communication Act (THCA), all employees who work in non−exempt areas are required to be informed
of the chemical hazards in their respective workplace by means of container labeling, Material Safety Data Sheets (MSDS’s)
To comply with the THCA, the following actions will be taken:
- The Supervisor/Safety Coordinator must have a Hazard Communication Program, which is accessible to employees on all work shifts.
- The Supervisor/Safety Coordinator must ensure that all containers for products containing hazardous chemicals are properly labeled.
- The Supervisor/Safety Coordinator must ensure that all employees know that the University has a centralized collection of MSDS’s located in EH&S (303 Drane Hall). Copies of MSDS’s may be requested by sending a memorandum to EH&S at MS 1090.
- The Supervisor/Safety Coordinator must provide the following information and training to all employees working in a non-exempt area:
- THCA requirements
- Location and availability of the written Hazard Communication Program
- Identify chemicals or chemical products present in the workplace operations
- Physical and health effects of the hazardous chemicals
- How to use the identified chemical products safely
- Reading labels and MSDS’s to obtain appropriate hazard and safety information
- Training must be documented and the documented file is to be kept within the department for 10 years.
For non−exempt areas, the department’s Hazard Communication Program must be permanent and continuous. When new products are received, an MSDS must be made available and, if the product introduces a new hazard to the workplace, all employees must receive training on the addition of new hazards prior to working with the hazardous substances.
The MSDS requirements are set by the Occupational Safety and Health Administration (OSHA). TTU EH&S will assist the Department of Chemical Engineering in determining if the chemical requires a MSDS. Obtaining a MSDS from the supplier or distributor should be first. If the MSDS is not accessible, work with EH&S to find the appropriate MSDS. If a single laboratory contains a significant amount of chemicals the MSDS’s will be stored alphabetically in properly labeled notebooks designated to its respective work area. Otherwise, a complete MSDS list will be kept in the main Chemical Engineering room 210. Access to MSDS’s will be allowed to ALL personnel who enter each work/laboratory area.
Interpreting Material Safety Data Sheets
Although MSDS’s are provided in various formats, every one will contain the following information:
- Identity − The product name and common synonyms used for the product.
- Physical & Chemical Characteristics − Contains general but very important info like:
- Flash point
- Vapor pressure
- Specific gravity
- Boiling point
- Freezing point
- Physical Hazards − Information concerning the potential for fire, explosion, or reaction is found here. The necessary extinguishing agent is also located here along with possible incompatible materials.
- Health Hazards − Information about the signs and symptoms of overexposure, acute and chronic health effects from a product. Should be used as an indicator of overexposure or sensitivity.
- Primary Routes of Entry − Common ways a product can enter your body are:
- Ingestion (mouth)
- Inhalation (mouth)
- Absorption (skin)
- Contact (skin)
Exposure Limits − Limits are set by many governmental programs. These can be in parts per million (ppm) or
milligrams per cubic meter (mg/m3) and are based on an 8−hour time−weighted average (TWA)
for a 40−hour workweek.
- Occupational Safety and Health Administration (OSHA)
- Permissible Exposure Limit (PEL)
- American Conference of Governmental Industrial Hygienists (ACGIH)
- Threshold Limit Value (TLV)
- National Institute of Occupational Safety and Health (NIOSH)
- Recommended Exposure Limit (REL)
- Occupational Safety and Health Administration (OSHA)
- Carcinogenic Effects − Information on whether the substance is a know carcinogen (cancer−causing agent). Produced by the National Toxicology Program (NTP) or the International Agency for Research on Cancer (IARC), or OSHA. These products need special caution when handling and require written procedures for storage and use.
- Handling Data − Special precautions for handling and use. Appropriate hygiene practices, decontamination procedures, and spill and clean−up actions are found here.
- Control Measures − Data concerning engineering controls, work practices, administrative controls, and personal protective equipment (PPE). These are based on worst−case scenarios, but must be followed unless EH&S has performed an evaluation and informed you in writing that less stringent controls will be satisfactory.
- Emergency and First Aid Procedures − Necessary emergency response and first aid procedures are detailed here. Remember when reading this information that it is assumed 6 that you have the required training and equipment to perform any emergency response or rescue actions discussed. If training is not adequate then call 911.
- Date of MSDS Preparation − The most current updated MSDS from the manufacturer is noted. Make sure you have the most recent published MSDS from the manufacturer of your product.
- Manufacturer’s Data − Information about the manufacturer such as name, address, and telephone number. This information can be used to access additional information on the hazardous substance or emergency procedures, if necessary.
These are all the areas that must be included on the MSDS’s. It is very possible that additional information will be included.
Labeling Containers and Chemicals
Labeling is mandatory on every container that contains a stock solution/chemical. Labels are also mandatory to mixtures from stocks or other mixtures. On each label, the chemical name and concentration should be present along with hazards or safety precautions.
Reporting Safe Activity
In compliance with OP 78.29, the Texas Tech University Chemical Engineering department will provide an annual safety activity report to EH&S by the fifteenth of September. Using form SAR−93, record data from the previous fiscal year.
Hazardous Waste Disposal
The key to disposing of hazardous waste is to minimize the amount of waste present. This is can be accomplished by several ways. They are:
- Surplus chemicals can be exchanged among laboratories, sections, or departments. This applies not only to ‘virgin’ materials, but to the end products of processes or experiments which could be of use to someone else.
- Materials may be distilled to recover them to a point of usability, if not to the original user, to another user on campus. This is greatly facilitated by segregating potential wastes to the extent practical at the point of generation.
- Substitution of a less hazardous material for one requiring special handling will not only cut disposal costs, but reduce hazards in the laboratory as well.
- Microscale operations reduce the waste volume by proportionately reducing the amount of chemical input for the reaction.
- Neutralization − Acids and Bases, uncontaminated with substances of a different hazard category, can be treated to bring the pH within the range of 5 to 9 and washed down the drain with 50 times their volume in water. There is no reason to turn in materials that can be neutralized at the point of generation.
- Steps must be taken to ensure faculty and staff members do not depart until all substances in their respective work areas are clearly marked as to contents. Compliance with the Texas Hazard Communication Act will eliminate most problems of this type, however, the cost of 7 analysis for the identification and hazard classification of unknowns is high enough to make this a cost effective endeavor.
Once determined the chemical cannot be exchanged, recycled, or neutralized, contact EH&S to arrange for it to be picked
up for entry into the waste stream.
Waste is picked up on Tuesday and Thursday every week. Do NOT allow wastes to accumulate, as this is a potential health and safety risk. Upon notifying EH&S for a waste pickup, you will need to provide the following information:
- Name and telephone number
- Department and room number of requestor
- Department and room number of waste
- Type(s) and number(s) of container(s)
- Whether or not the "REQUEST FOR HAZARDOUS WASTE PICK−UP & DISPOSAL" form is complete
This information is necessary for proper disposal and should be available prior to contacting EH&S for the pick−up. The EH&S labels are to be affixed to each separate container of hazardous waste.
General Laboratory Policies
The following policies apply to all students − undergraduate (UG) and graduate (G), faculty, and staff working in departmental laboratories, research facilities, and at field locations. Any violation of these policies will result in suspension of laboratory and research privileges.
- Students injured in the laboratory are responsible for their own medical bills. Insurance is not provided by the University to cover medical bills incurred by a student.
- All undergraduate students must complete appropriate safety training. This safety training will be conducted during the first laboratory session; a student missing the safety training will be dropped from the respective course. For graduate students, a safety seminar will be provided annually, usually at the beginning of the fall semester.
- Students must review the MSDS’s before using any chemicals.
- Many experiments are hazardous if not conducted properly. Ask the laboratory instructor about safe operating procedures.
- Students must operate all laboratory equipment safely. Use of designated personal protective equipment (PPE) is required when in the laboratory. Each laboratory carries different requirements for PPE, so use the PPE that is required by your laboratory.
- If a dangerous situation is observed by a student, notify your instructor. Common dangerous situations: broken glass, chemical spill, laboratory misuse, etc.
- Students are required to wear appropriate laboratory clothing (this may include long−sleeved shirts, long pants, closed−toe shoes, safety goggles, gloves) that is not loose or bulky to eliminate the possibility of being caught in machinery/laboratory equipment.
- Fire extinguishers are marked. In case of fire, Call 9−911.
- Some laboratories are equipped with eyewash and shower stations. Wash off any chemical that makes skin contact, or and foreign material that falls into the eyes IMMEDIATELY.
- Common sense by faculty, staff and students is very important to laboratory safety. For example container labeling, picking up tripping hazards and other distractions.
- No hazardous laboratory equipment or machinery may be operated by students without at least two people present.
- Use proper lifting technique when lifting and carrying heavy items. If needed, ask for help.
- Building access after hours:
- It is the responsibility of the academic supervisor to be fully aware of all after−hours laboratory work being performed by a research/graduate student, and to ensure the safe undertaking of this work.
- A notice in a prominent location stating your contact details emergency instructions must accompany any experiment running overnight or over a weekend.
- It is the graduate student’s responsibility to inform the supervisor and laboratory manager of intended after hours experimentation. Please provide your mobile phone number and home phone contact numbers in case of problems.
- Avoid, at all possibilities, working alone in the laboratory after hours. Do not perform dangerous experiments at night or on the weekends without permission and always have someone there with you in case of an emergency.
- No work with radioisotopes is to be performed after normal working hours without supervision by a licensed Radiation Safety Officer.
- Children are not permitted in any laboratory.
- In case of an emergency, first remove subject from unsafe environment and administer first aid. Notify emergency personnel if needed.

Chemical Engineering Department and Facilities
The five different areas of the Chemical Engineering Department are: main building, annex, Petroleum engineering, Experimental Sciences Building and the Livermore Center. Each laboratory within each building has designated purposes and thus each area can cause different degrees of hazards. For these reasons, access to many of these areas is limited. Talk to the chair, safety coordinator, or academic supervisor for access and relevant safety information. There is one teaching laboratory. All the other laboratories are research laboratories and they fall under the same set of rules, regulations and safety hazards.
- Doors locked at all times.
- Safety glasses and hard hats required.
- Watch for head clearance areas marked with tape and make sure fan is always on.
- Acids, bases, flammables and corrosives. Use flammable storage cabinet.
- Broken glass container.
The other laboratories in the chemical engineering department follow the same rules as described in the general laboratory procedures.
Emergency Action Plans
These are the plans for when an emergency is deemed necessary. When an emergency arises, the plans should be followed to protect
yourself and the lives of other.
In case of a fire, everyone should evacuate to the closest exit maintaining they do not put themselves in harms way. Do not use the elevators. Take the stairs! Each laboratory has established guidelines to exit the laboratory and then exit the building. Maintain a proper distance from the building in case of explosions. Do not block the roads in order for firefighters to reach the building.
In case of a tornado, all faculty, staff, students and guests should safely move to the middle corridor of the basement. Make sure to stay away from windows.
In case of a shooter on campus or within chemical engineering buildings, everyone must move to a room and, if possible, lock the door behind them. The hallway should be exited and direct line of sight to the hallway should be avoided at all times.
