Time Saving Techniques for Complying With EPA's Remodeling Lead
Safe Work Practices Mandate
If remodeling contractors aren’t already aware, the game has changed due to a new federal mandate. Contractors remodeling homes pre 1978
must have lead safe training by April 22, 2010 and comply with the regulation. These lead safe work practices can be a daunting and time
consuming task for inexperienced remodeling contractor. The extra man hours can add up on a given project and consume profits. This article
attempts to give some insiders “tricks of the trade” from a former Grand Rapids remodeling lead abatement contractor to help reduce man hours
and keep material costs down while complying with the new mandate.
Plastic sheeting is your friend. Known as “poly” to abatement contractors, it covers your work area and makes for quick clean-up. Always
purchase clear poly. As suggested by the EPA standards, cover the floor at least 6 feet out and construct walls with 4 or 6 mil. In addition, place
a sizeable scrap of the heavier poly in the middle of the work area before covering the floor. This scrap will come in handy during tear down.
The author has found 12’ widths are most useful. This covers nearly any ceiling height, and accommodates traditional floor plans for most rooms
so there’s less splicing.
Be sure to have two kinds on hand. Painter’s plastic can be used to cover shelves and articles around the room. It’s far less expensive and
comes in handy for just covering the odds and ends.
Cut a runner from containment to the dumpster before work begins. Make it wide enough to carry supplies and materials. During rainy weather,
make sure there is a mat of some kind to wipe workers feet before reentering the house. Poly is very slippery when wet.
Demo materials are often sharp and heavy. This is a problem when bagging the debris as the sharp edges poke holes in the bag and a trail of
dust marks your path to the dumpster. A solution and time saver is to have plenty of garbage cans on hand. The trick is to fill the garbage can
with the liner inside containment. When full or heavy enough, gooseneck it and leave in the container. The container can then be hauled to the
dumpster and disposed of.
When dealing with heavy dense debris, it helps to have a container with wheels, as dragging a heavy garbage can will eventually wear holes in
the poly runner. As demo proceeds, the bags should be staged at the doorway within easy reach. The bags or garbage cans should be grabbed
from outside containment to save time going in and out of the doorway. Also, have one worker in containment stage the bags by the door and
one worker outside that can reach in and grab them.
For a plaster tear out, an old piece of paneling can help workers have a place for the plaster to “land”. It’s also useful to scoop up the debris and
bag. The paneling should be placed finished side up so there is a sealed side to vacuum up or wipe down. Any wood product is fine as long as
it’s painted or sealed. Open wood is one of the most difficult to clean for lead dust, as the open pores and grain of the natural fiber harbor and
lock in the dust. 5 gal buckets can be used for dumping the old broken plaster. Just line them with 6mil small kitchen size bags and carry the
bucket to the dumpster.
When work is done, take the walls down first and collapse them gently on the floor poly. Then simply roll up the walls and the floor on the scrap
you first laid down to dispose. This scrap catches the inevitable debris that escape from the roll when fitting it in the garbage bag and saves the
time of vacuuming. The scrap can now be rolled up and disposed of also. After a contractor gets a few jobs under their belt, set up and tear down
should go quickly.
The new EPA standard expects the remodeling contractor to isolate the work area, utilizing temporary poly walls. This is a standard in the
abatement industry, and can be done quickly and efficiently no matter what the size or shape of the project.
The method of affixing the containment walls must first be addressed. Many contractors often tape the poly to the ceiling, forming a perimeter
around the work area. This is acceptable and common, but has several issues. First and foremost it is very time consuming, also it can be very
difficult to attach the tape to a textured ceiling or uneven surface. Due to the weight of the poly, the tape can fail and bring the wall down. The
work must then be halted and time taken to reattach it. Finally, upon removal, the tape can peel and destroy the surface it was stuck to. These
issues can be costly and add many man hours to a simple project.
Consider extendable poles. These poles are reusable, reducing labor and issues associated with using tape. Often marketed as cargo bars for
pickup trucks, these ratcheting poles extend and clamp the poly to the ceiling no matter what the height or surface. The poles also negate the
problems of disturbing the wall and tape destroying the surface upon removal. Although prices differ throughout the region, extendable ratcheting
poles can be purchased inexpensively.
Plan the containment area by ratcheting the poles in place where the wall will be. Give yourself plenty of room to work, and plan an area by the
containment entrance to stage the bagged debris. Once the poles are where you want them, roll out the poly and wrap it around the poles,
defining the perimeter and determining the length. Give yourself a little extra, it’s no fun trying to stretch poly to the wall.
Having the poly cut to size, start unfolding it at one end to the full width. With a step ladder, take the tension off the first pole and tuck the
plastic over the pole. Then ratchet the pole up, trapping the poly between the ceiling and the pole’s top foot. Repeat the process going down the
length of the wall. Finally, tape the edges to the walls to seal the containment. The time it takes to set up the walls is of course determined by
the size of containment but is far less then taping the poly to the ceiling without the issues of tape.
With the walls now complete, the doorway needs to be installed. It is important to limit the dust that migrates but also permits workers egress.
Remember that all bags of debris and materials have to pass through so make it big enough. As described before, a staging area should be
planned in containment by the door area.
Many times the worker can use an existing door and just attach the poly door to it. A time saver is to make a poly door that is reusable. First,
cut a piece to fit over a standard size door. The measurement of the poly should be 38” X 84”. Cut the upside down “T” and covering dust flap.
Now, apply duct tape around the perimeter and fold over the edges making a “picture frame” around the edge. Duct tape the flap over the “T”. The
masking tape to attach the poly to the casings can be removed and applied over and over without tearing the poly. At the end of the job, just roll
it up for the next project. The reusable door should be able to be installed in 2 or 3 minutes vs. taking 10 to 15 minutes to make a new one every
time.
Although white suits are not required by the EPA mandate, they are nice to protect the worker from bringing home the dust after work. Putting
on a white suit and removing it after leaving containment is far faster than vacuuming off all the workers clothing, but there are some things to
consider.
White suits are sized small, medium, large and extra large. Purchase them at least a size bigger than the workers shirt size. During years of
abatement work in white suits the author has found “large” is generally the size used by most, save for the most portly of workers that might
need an XL.
During the summer, work in white suits can be very hot. Working in shorts and t shirts is acceptable but the temptation to shed any more
clothing should be avoided. White suits are translucent and nobody wants to see more of their fellow worker than need be.
White suits generally come in one piece with footies. These footies tear during work very easily and will be tripping the worker in no time. Since
the EPA guidelines are not abatement the footies can be cut off at the ankles and the ends taped with masking tape around the ankle. This will
give much more traction and ease of movement.
Negative air is the key to keeping dust from migrating past containment. The importance of an air mover in containment cannot be overstated. It
will save the contractor many hours of cleaning the perimeter of the containment due to the inevitable escaping dust through the door. Without
proper ventilation, the air inside of containment can get saturated with dust from demo, making the work dangerous and intolerable.
Many companies sell them in a variety of styles and sizes. They can be readily looked up online and be purchased ready to go out of the box.
These units can be pricey and the small business owner may consider them out of reach. The author has several units that were all constructed
in house costing under $100.00 a piece. The following is a guide to constructing one in house for the small business owner.
Whether purchased or built in house air movers all do the same thing, move air. The higher the air exchange rate, the better but since they are
carried to every site, size becomes an issue. The typical width should not exceed 30” and best if the total width is less than 24”. Most interior
doorways are smaller than the 36” standard entry door. Remember the EPA’s mandate is homes pre 1978, and as most remodeling contractors
already know older homes doorways can be small. The size of the unit is not as critical as the volume of air it moves per hour with the squirrel
cage.
Squirrel cages from residential HVAC systems can normally be purchased cheaply to move the air and are a good choice for an air exchanger.
Make sure it is clean and in good working order. The squirrel cage can be mounted to any material of choice, but the unit must be air tight and
be able to be wiped down. Wood is fine as long as a quality semi gloss is applied for clean up. Handles and wheels are very useful and should
be included; remember the unit has to be portable.
The intake for the dirty air should be filtered to save the squirrel cage from clogging up with dust. Although an exhaust tube can be used to expel
the dirty air, there are times when there isn’t a nearby window or door to use and the air inside of containment must be expelled indoors. In that
situation, the air must be HEPA filtered to remove potential lead dust. A typical home furnace filter unit that holds two standard air filters can be
incorporated in the air mover for this issue. The first air filter should be a less expensive model that filters out about 90% of the airborne particles.
This filter will save the second expensive HEPA filter behind it from clogging up quickly. It can also be vacuumed off every so often and cleared.
The cheaper filter can be thrown away after the job is complete where the expensive HEPA can be reused. After the work is complete, the HEPA
should be vacuumed and stored in a clean, sealed plastic bag.
A standard metal ductwork fitting can be installed on the air mover to attach the exhaust tube to. The tube is taped to the fitting and exhausted
out a window or door. The tube itself can be purchased at an abatement supply house or found online. With the unit caulked and painted it’s
ready for the first job.
The air scrubber should be mounted to the poly wall. Placing the air scrubber in the containment area gets in the way and the exhaust tube can
be tripped over and damaged. Furthermore, the unit will have to be vacuumed and wiped down after every use. A far better and faster way is to
attach the air scrubber to the poly wall outside containment. Simply wheel the air scrubber up against the poly wall and with a sharp utility knife,
cut around the filter area. Blue tape or masking tape can be used to seal the cut opening to the metal air scrubber’s filter housing.
Hopefully these tips will help the small remodeling contractor survive the new EPA mandate. A current Grand Rapids remodeling contractor, the
author will be struggling with the new ruling with the rest of the industry.
