The WRSC laboratory comprises of rooms in two building at the 推荐杏吧原创 (UNR): Harry Reid Engineering Laboratory (HREL) (Building Code: 065) and Scrugham Engineering and Mines (SEM) (Building Code: 056).

  • Rooms in HREL: 103 (Aggregate Lab), 200 (Binder Lab), 201 (Mixing Lab), 202, 203, 204, 205, 209 (-18°C Freezer), 210 (5°C Freezer).
  • Rooms in SEM: 112, 116 & 116B (Cutting Room).

Floor plans of the two buildings are included at the end of this manual showing the various rooms that are part of the PES program.

 

Principal investigator responsibilities

The Principal Investigators (PI) have the primary responsibility for ensuring that their laboratories are safe. They must adhere to all guidelines and regulations. They are responsible for the safe use of biological (if applicable), chemical and radioactive (if applicable) substances in their laboratory.

In addition, the PI must:

  • Limit personnel, student, and visitor exposure to hazards to the lowest practical level
  • Develop lab specific safety procedures and train their personnel on them
  • Maintain documentation of training
  • Provide personal protective equipment (PPE) and instruction on use
  • Ensure waste is properly disposed
  • Report spills, exposures, or incidents to Environmental Health & Safety (EHS): EH&S 24-hour emergency line 327-5040
 

Laboratory staff/student responsibilities

  • Know the materials and procedures used in the laboratory
  • Follow safety guidelines and procedures
  • Know the emergency procedures
    Complete required laboratory safety training
  • Report unsafe conditions to lab supervisor, PI, EH&S
  • Utilize all required PPE

  1. Isolate area and if possible contain the spill
  2. Contact the Biosafety Officer (BSO) at EHS and Hazardous Waste Manager (HWM) immediately, and PI

BSO: Ben Owens 775-327-5196
HWM: Woody Wright 775-784-1987
PI emergency numbers: 775-784-1180

 

Fire alarms/extinguishers

Locations of fire pull station alarms and fire extinguishers: Refer to egress maps located on the walls in various locations throughout HREL and SEM. Egress maps for SEM are located by the doors of SEM rooms 116 and 112. Egress maps for HREL are by all stairways and entrances. Egress maps have also been included at the end of this safety lab manual for HREL 1st and 2nd floors and SEM 1st floor.

Know the location of each of these, and identify the location of the extinguisher closest to your lab bench. If the fire alarm sounds, leave the building immediately and move away to a safe distance. Take note of assembly areas on the egress maps.

 

Eyewashes and safety showers

All laboratories and chemical storage areas must have ready access to an operating eyewash, with a safety shower generally required as well. Recommended maximum travel time for an affected individual (assume eyes have been splashed with chemical) is 10 seconds, with a maximum travel distance of 100 feet.

In the event of a personal contamination, prompt flushing of the affected area is necessary to minimize harm to the affected person. Keep the eyewash/safety shower area free of obstructions, and easily accessible.

  • Location of safety showers: Refer to the egress maps provided at the end of this manual.
  • Location of eyewashes: Refer to the egress maps provided at the end of this manual.

In case of exposure, proceed to nearest eyewash station. Hold eyelids open with thumb and forefinger and rinse for at least 15 minutes. Wash from the outside edges towards the inside to prevent washing hazardous materials back into the eye.

Rinse should be aimed at the inner corner of the eye (near the nose) not directly at the eyeball. “Roll” eyes around and up and down to ensure full rinsing.

Contact lenses (if worn) should be removed as soon as possible. Have another member of the lab call for emergency response immediately. The area around the eye wash station must remain clear at all times.

 

First aid kit

All personnel must be aware of the locations of the first aid kits in all WRSC laboratories. The signs are displayed in the laboratories to show the locations.

 

Exposures in the laboratory

All exposures must be reported to the PI and to EH&S.

Chemical exposure

For most chemical exposures to the skin, wash the chemical off with water for at least 15 minutes and remove any contaminated clothing. Use the sink for small exposures; for large exposures use the safety shower.

Molten asphalt cement exposure

First aid procedures in case of asphalt cement burns are posted in the doors of both the binder lab (HREL 200) and mixing lab (HREL 201). Procedure is also given below:

In the event of a molten asphalt cement burn, cool the asphalt cement and affected parts of the body immediately.

Methods of cooling (in order of preference)

  1. Completely submerge affected area in ice water
  2. Completely submerge affected area in tap water
  3. Place affected area under running water

Do not delay!

Use any available water, cooler than body temperature, while arranging for better cooling.

CAUTION: DO NOT apply ice directly to affected area as it may cause cold burns.

Proceed with the following:

Minor asphalt cement burns

At first opportunity get victim to physician. Includes:

  • Injury to small areas of fairly insensitive flesh involving a small quantity of asphalt cement

Serious asphalt cement burns

As soon as possible get the victim to the hospital.  Includes:

  • Injury to the head, face or extremities;
  • Injury when large amounts of asphalt cement are involved;
  • Evidence of nausea or faintness.

Safety procedures

Good practices

  1. Safety is paramount.
  2. Horseplay is ABSOLUTELY NOT ALLOWED anywhere in the lab.
  3. Lab personnel wash their hands after working with potentially hazardous materials and before leaving the laboratory.
  4. Lab personnel must not perform any tests or use any equipment unless they have been trained to properly/safely perform/use them.
  5. Perform tests carefully and do not rush.
  6. Eating, drinking, smoking, smokeless tobacco, handling contact lenses, applying cosmetics, and storing food for human consumption is not permitted in laboratory areas. If food is stored, it is done so outside the laboratory area in cabinets or refrigerators designated and used for this purpose.
  7. Clean up after your work space after you are finished for the day.

Cutting and coring asphalt mixtures

  1. Always cut or core in a controlled manner
  2. Always wear safety glasses and ear muffs/plugs
  3. Be aware of body parts and keep them away from machine parts (saw) that may potentially crush or cut

Aggregate lab

  1. Always have the rollup door open and the large industrial fan on whenever you commence work in the aggregate lab
  2. A N95 particulate respirator is encouraged. Information on NIOSH N95 particulate respirators that are provided for this lab are included in the back of this manual. Respirators are located in the storage room of HREL 200.
  3. Safety glasses must be worn!
  4. Some of the aggregate bags and pans are heavy. Make sure to lift with a good posture and to use your legs (not your back) whenever you are picking them up. If it’s too heavy for just you to pick up, ask for help

Mixing/compaction lab

  1. Always protect yourself from hot surfaces. Wear long sleeved shirt and lab coat. Never wear sandals or open-toed shoes. Long pants are also required.
  2. When compacting beams/ HVEEM samples/ Marshall samples/gyratory samples, always be aware of where your body parts are. Hydraulic compactors are unforgiving and WILL easily crush your fingers.
  3. When using D-Limonene to clean utensils and equipment, make sure to not breathe in the vapors and try to work in the hoods as much as possible.
  4. When using WD-40 to clean utensils and equipment, avoid breathing in the vapors.
  5. Be wary of the heating gels used during mixing. Keep flames away from you and your clothing.
  6. Never rush when dealing with hot asphalt binder! Rushing can increase the chances for splashes and consequent burns!

Binder lab

  1. Always protect yourself from hot surfaces. Wear long sleeved shirt and lab coat. Never wear sandals or open-toed shoes. Long pants are also required.
    Never rush when dealing with hot asphalt binder! Rushing can increase the chances for splashes and consequent burns!

Large-scale testing lab

  1. Always wear the hard hat when you are inside the lab.
  2. A N95 particulate respirator and safety glasses are recommended when working with subgrade, base, and /or asphalt mixtures.
  3. Get proper training from the laboratory manger or department technician before using any tools in the lab
  4. Always use a properly secured ladder when reaching objects above your head level

Safety equipment

  1. Protective eyewear (goggles) is worn when conducting procedures that have the potential to create splashes hot asphalt binder or hazardous materials. All personnel MUST wear safety glasses at all times.
  2. In addition to goggles, face shields are recommended when transferring hazardous materials such as asphalt solvents from one container to the other.
  3. Gloves are worn to protect hands from exposure to hazardous materials. Hot Mill gloves are worn to protect hands from exposure to hot surfaces. Glove selections based on an appropriate risk assessment. Hands are washed prior to leaving the laboratory
  4. Gloves are changed when contaminated, integrity has been compromised, or when otherwise necessary.
  5. Gloves are removed and hands are washed when work with hazardous materials has been completed and before leaving the laboratory.
  6. Dust masks are changed when contaminated, integrity has been compromised, or when otherwise necessary.
  7. Disposable ear plugs are not washed or reused. Used ear plugs are disposed of at the end of the day.
