Prior to beginning work at a site, an evaluation of the structural integrity of the building as well as potential hazards should be made and the dangers should be managed.
Structural Integrity
Signs of poor structural integrity:
Walls slanted, tilted or bowed
Building tilted
Severe cracks in walls or ceilings
Evidence of building movement
Floors uneven or slanted
Structural support beams or pillars moved or missing
Excessive floor or ceiling loading such as trees on roof or wet debris piled high
Detached or weakened stairways
Note: Buildings that appear to be unsound should not be entered.
Potential Hazards
Upon evaluation, note the following hazards:
Mercury
Live electrical wire
Remaining floodwater
Potential for trips and falls
Water and debris may hide trip and fall hazards
Falls from heights
Holes in flooring
Slippery surfaces
Excessive floor debris
Confined spaces/poor ventilation
Wildlife
Sharp edges
Protruding nails
Broken glass
Bent or broken metal
Potential overhead dangers
Trapped water
Unstable ceiling material
Unsecured fixtures
Threatening/violent occupants
Gases
Oxygen deficiency
Explosive gases
Toxic gases
Airborne particulates
Dust
Asbestos
Lead
Mold
Risk Mitigation
PPE (Personal Protective Equipment)
Suggested PPE:
3M Half-face respirator with p100 filters
Gloves
Boots
Tyvek suit (optional)
Safety goggles (optional)
Proper usage and instruction for PPE:
Respirator Wear: Always make sure that the 3M Half-face respirator has a good fit. One way to test this is while in normal wear put both hands covering the vents and suck in. This should tighten the mask and create a sucking feeling to your face. If you don't have this feeling you should resecure the mask on your face.
Tyvek Suit Wear: Make sure that the tyvek suit is loose enough that you can move around comfortably without it binding. But remember you do not want it to be so large that it gets caught on everything you walk past.
Management of health
Hydration
try to drink twice as much as you think you need
Sanitation
Rinse your hands then sanitize before touching anything
Do not touch your face or food with unsanitized hands
Nutrition
Even if you are not hungry eat something its hard work you need the energy(no meal skipping)
Securing the work site
Danger: Solution: Poor structural integrity Do not enter house, mark visibly as unsound or dangerous, report to supervisor Live electrical wire in structure Turn off main electrical switch in breaker box Live electrical wire outside of structure Contact energy company and do not approach live wire Tripping and falling Clear paths prior to continuing work. Secure or mark holes or uneven flooring. Confined spaces/poor ventilation Do not work extended periods of time in such spaces, if there are windows try to open them so that some fresh air can circulate. Wildlife Do not approach and assume as dangerous. For larger wildlife, contact animal control Sharp edges Mark or remove prior to continuing work Overhead dangers Remove prior to continuing work Threatening or violent occupants Do not confront. Alert supervisor and authorities (if necessary) and leave premisesMake sure water to the house is offAround the outside of the building there will be a pipe coming out of the ground to a spigot then into the building. If you look at the base of the pipe you will find a valve(you might have to dig a little) close the valve.MercuryThe most common places to find mercury is in old thermostats. You can just remove the mercury from the thermostat and put it in a container, and place it in the EPA pile. If there is a mercury spill evacuate the house and call the EPA
Safe work practices
Always be aware!
Know where coworkers are in relation to you
Be mindful of surroundings at all time
Listen for the sound of a generator if there is a trailer near where you are working the electric could still be on
Make sure that the gas meter has pulled and if not make sure that the meter reads zero or that there is a plug and or the pipe is disconnected from the house
Tools and Equipment
Do not attempt use of equipment without prior experience or guidance from more experienced coworker
Use great caution when swinging, hammering, or operating machinery
If you are not using a tool i.e.: a hammer or crowbar do not place it on the ground, use window sills or hang them. Keep track off all your tools what you have and how many of them
Cleanup
Unplug all electrical equipment after use
sweep up all dust and debris
Have two separate people make a tools sweep through the house one after the other
Return all tools to designated storage areas/containers
Sanitation
Wash(always rinse your hands first)/sanitize hands before eating/handling food
Do not rub eyes or touch face while working
Hydration
Continue hydrating throughout the day
Take as many breaks as needed
immediately cease work when feeling dizzy or experiencing headaches and notify site manager
Drink at least a bottle of water every hour
Alleviation
Ask your site manager if there is a port-a-pot near your work site
First Aid and Emergency Care
First Aid
If you seek outside medical attention, make sure to report to your supervisor and fill out an incident report
If a person is having pain of any sort, trouble breathing, etc - the acronym OPQRST can be used to ask the appropriate questions:
Onset (When did it start?)
Provocation (Does anything make it better or worse?)
Quality (Can you describe the pain?)
Radiation (Does it move or stay in the same place?)
Severity (On a scale from 1-10 what is your pain?)
Time (How long has it been going on?)
Cuts and Scrapes:
If wound is severe:
Always wear gloves when helping others
Stop the bleeding by:
- applying pressure to the wound
- elevating the wound
If bleeding does not stop, apply pressure to nearest artery and call 911
Watch for signs of shock
If wound is minor:
Clean the wound
Apply an antibiotic
Cover the wound
Change the dressing
Get stitches for deep wounds
Watch for signs of shock
Get a tetanus shot
Punctures:
If object is embedded in skin, do NOT remove it
Apply gauze around object to control bleeding and prevent movement
Watch for signs of shock
Foreign Object in Eye
To help someone else:
Put on gloves.
Seat the person in a well-lighted area.
Examine the eye to find the object. Pull the lower lid down and ask the person to look up. Then hold the upper lid while the person looks down.
If the object is floating in the tear film on the surface of the eye, try flushing it out. If you're able to remove the object, flush the eye with a saline solution or lukewarm water.
Caution
Don't try to remove an object that's embedded in the eyeball.
Don't rub the eye.
Don't try to remove a large object that makes closing the eye difficult.
When to call for help:
You can't remove the object.
The object is embedded in the eyeball.
The person with the object in the eye is experiencing abnormal vision.
Pain, redness, or the sensation of a foreign body in the eye persists after the object is removed.
Head Trauma
Dial 911 or call for emergency medical assistance if any of the following signs are apparent:
Severe head or facial bleeding
Clear substance appears in ears/nose/mouth
Change in level of consciousness for more than a few seconds
Black-and-blue discoloration below the eyes or behind the ears (known as Battle Signs)
Cessation of breathing
Confusion
Loss of balance
Weakness or an inability to use an arm or leg
Unequal pupil size
Repeated vomiting
Slurred speech
If severe head trauma occurs:
Keep the person still.
Stop any bleeding.
Watch for changes in breathing and alertness.
Heat Exhaustion
Signs and Symptoms:
Feeling faint
Nausea
Heavy sweating (diaphoresis)
Ashen appearance
Rapid, weak heartbeat
Low blood pressure
Cool, moist skin
Low-grade fever
If you suspect heat exhaustion:
Get the person out of the sun and into a shady or air-conditioned location.
Lay the person down and elevate the legs and feet slightly.
Loosen or remove the person's clothing.
Have the person drink cool water, not iced, or a sports drink containing electrolytes.
Cool the person by spraying or sponging him or her with cool water and fanning.
Monitor the person carefully. Heat exhaustion can quickly become heatstroke. If fever greater than 102 F, fainting, confusion or seizures occur, dial 911 or call for emergency medical assistance.
Sprains
Follow the instructions for P.R.I.C.E.
1. Protect the injured limb from further injury by not using the joint.
2. Rest the injured limb.
3. Ice the area.
4. Compress the area with an elastic wrap or bandage.
