Welcome to the Citizens Guide to Hazardous Materials (HAZMAT) Emergencies. Hazardous materials are common throughout our community. They are used by industry, business, government, agriculture, and private citizens on a daily basis. Knowing what to do and what not to do when hazardous materials are involved in an emergency can prevent injury and save lives..

Hazardous materials are chemical substances, which if released or misused can pose a threat to the environment or health. These chemicals are used in industry, agriculture, medicine, research, and consumer goods. Hazardous materials come in the form of explosives, flammable and combustible substances, poisons, and radioactive materials. These substances are most often released as a result of transportation accidents or because of chemical accidents in plants.
A hazardous materials accident can occur anywhere. Communities located near chemical manufacturing plants are particularly at risk. However, hazardous materials are transported on our roadways and railways daily, so any area is considered vulnerable to an accident.
Learn to detect the presence of a hazardous material. Many hazardous materials do not have a taste or an odor. Some materials can be detected because they cause physical reactions such as watering eyes or nausea. Some hazardous materials exist beneath the surface of the ground and can be recognized by an oil or foam-like appearance.
Contact your Local Emergency Planning Committee, (LEPC) or local emergency management office, (Houston or Harris County OEM) for information about hazardous materials and community response plans. Find out evacuation plans for your workplace and your children's schools. Be ready to evacuate. Plan several evacuation routes out of the area. Ask about industry and community warning systems.
Prepare for the worst. Have disaster supplies on hand.
- Flashlight and extra batteries
- Portable, battery-operated radio and extra batteries
- Plastic sheeting pre-cut to fit windows and doors of your safe room
- Duct tape, masking tape, plastic wrap
- Games and other things to keep small children occupied
- First aid kit and manual
- Emergency food and water
- Non electric can opener
- Essential medicines
- Cash and credit cards
- Sturdy shoes
- Blankets, coats, strong clothing
Develop an emergency communication plan.
In case family members are separated from one another during a hazardous materials accident (this is a real possibility during the day when adults are at work and children are at school), develop a plan for reuniting after the disaster. Ask an out-of-state relative or friend to serve as the "family contact." After a disaster, it's often easier to call long distance. Make sure everyone knows the name, address and phone number of the contact person.
If you hear a siren or other warning signal, turn on a radio or television for further emergency information.
IF CAUGHT AT THE SCENE OF AN ACCIDENT
*** Do Not Drive through smoke or clouds at the scene***
they may contain hazardous chemicals!
- If you see an accident, call 9-1-1 to report the nature and location of the accident as soon as possible.
- Move away from the accident scene and help keep others away.
- Do not walk into or touch any of the spilled substance. Try not to inhale gases, fumes, and smoke. If possible, cover mouth with a cloth while leaving the area.
- Stay away from accident victims until the hazardous material has been identified.
- Try to stay upstream, uphill, and upwind of the accident as hazardous materials can quiickly be transported by water and wind. In general, try to stay at least one-half mile (10 city blocks) from the danger area; for many incidents you will need to go much further.
Assisting Victims
If are not trained in dealing with the hazardous material involved, Don't try to care for victims. If you don't know what the material is, wait until the substance has been identified and authorities indicate it is safe to go near victims. Taking such heroic actions works only in the movies. In real life the result is usually more victims. Once trained professionals have declared it safe to enter, you should:
- Move victims to fresh air and call for emergency medical care
- Remove contaminated clothing and shoes and place them in a plastic bag
- Cleanse victims that have come in contact with chemicals by immediately pouring cold water over the skin or eyes for at least 15 minutes, unless authorities instruct you not to use water on the particular chemical involved.
In Houston for emergency information, monitor the local Emergency Alert System (EAS) radio station for updates and remain in shelter until authorities indicate it is safe to come out.
In January 1997, the Emergency Alert System (EAS) replaced the old EBS or Emergency Broadcast System.
Close all doors to the outside and close and lock all windows (windows sometimes seal better when locked)
Building superintendents should set all ventilation systems to 100 percent recirculation so that no outside air is drawn into the structure. When this is not possible, ventilation systems should be turned off.
Turn off all heating systems.
Turn off all air-conditioners and switch inlets to the "closed" positions.
Seal any gaps around window type air-conditioners with tape and plastic sheeting, wax paper, or aluminum wrap.
Turn off all exhaust fans in kitchens, bathrooms, and other spaces.
Close all fireplace dampers.
Close as many internal doors as possible in your home or other building.
Select a room in the building where occupants can be the most comfortable and which is easy to seal off. This room should, if possible, provide access to water, toilet facilities, and adeqaute room for people to sit or lie down. the room should have a battery powered radio, snack foods, and bottled water.
Use tape and plastic food wrapping (Saran Wrap, Handi Wrap etc.),or aluminum wrap to cover and seal exhaust fan grilles, range vents, dryer vents, and other openings to the outside to the extent possible (including any obvious gaps around external windows and doors).
If the gas or vapor is soluble or even partially soluble in water -- hold a wet cloth or handkerchief over your nose and mouth if the gases start to bother you. For a higher degree of protection, go into the bathroom, close the door, and turn on the shower in a strong spray to "wash" the air. Seal any openings to the outside of the bathroom a best as you can. Don't worry about running out of air to breathe. That is highly unlikely in normal homes and buildings.
If an explosion is possible outdoors -- close drapes, curtains, and shades over windows. Stay away from external windows to prevent potential injury from flying glass.
Minimize the use of elevators in buildings. These tend to "pump" outdoor air in and out of a building as they travel up and down.
Tune into the Emergency Alert System Station on your radio for further information and guidance.
Authorities will decide if evacuation is necessary based primarily on the type and amount of chemical released and how long it is expected to affect an area. Other considerations are the length of time it should take to evacuate the area, weather conditions, and the time of day. If you are told to evacuate:
- Stay tuned to a radio or television for information on evacuation routes, temporary shelters, and procedures.
- Follow the routes recommended by the authorities--shortcuts may not be safe.
- If you have time, minimize contamination in the house by closing all windows, shutting all vents, and turning off attic fans.
- Take your pre-assembled disaster supplies.
- Your pets will also need to evacuate , take them with you.
- Remember to help your neighbors who may require special assistance--infants, elderly people and people with disabilities.
- Leave as soon as you can.
Return home only when authorities say it is safe. Follow local instructions concerning the safety of food and water. Clean up and dispose of residue carefully. Follow instructions from emergency officials concerning clean-up methods.
WORD FOR THE MEDIA
RESPONDING TO A HAZMAT INCIDENT
In the past, media people have been injured because they rushed into a hazardous materials situation without the necessary knowledge or respect for the danger involved. We include the following guidelines to help the media representatives make informed judgments relating to their safety.
Hazardous Materials, as defined by the US Department of Transportation, run the gamut from explosives to radioactive to poisons, compressed gases, flammable compressed gases, and combustibles. When approaching an incident involving railroad or highway transportation, there is always a possibility that hazardous materials are involved. The most likely prospect for personal injury comes from releases from tank cars or tank trucks, but hazardous materials are also carried in seavans, container stacks, and inside boxcars.
CHEMTREC, a part of the Chemical Manufacturers Association, offers the following suggestions for consideration when approaching a transportation accident:
