The works will be supervised by the Contractor’s foreman who has overall responsibility for the safe execution of the work on this project.
11.0 Environmental Impacts and Controls

Wash out container into contractor’s tank and dispose/recycle container off- site.
Acceptable
Chemical run-off
Run-off is to be kept to minimum or zero using good spray and brush control techniques. If run off to drains is unavoidable, block drains/gutters until application has been concluded.
Run-off to drains is to be kept to as near Acceptable
zero as possible using good spray and
brush control techniques. If run off to
drains is unavoidable, block
drains/gutters until application has been concluded.
Residue run-off from Due to the nature of Blackwash, any Acceptable diluted (5-10:1) BENZ Blackwash rinse water.
chlorine will disappear very rapidly. Oxidised molecules will be the dominant by-products of Blackwash. Chlorinated compounds have been viewed as the more important to assess from an environmental point of view because of the hazardous properties of certain types of chlorinated molecules.
Residue run-off of diluted BENZ Blackwash are relatively
biodegradable and are not
expected to bioacumulate.
Any residues entering water system are not expected to cause any harm to the environment.
Treated areas are to be left a minimum
of 30 minutes – and 60 minutes is
preferable – before rinsing to ensure no
chlorinated molecules remain.

12.0 Emergency Provisions In the event of an incident the following people shall be notified: Site emergency tel: N/A Security: N/A Contractor H&S leader tel: 07773560582 Client H&S leader tel N/A
12.1 First Aid
In the event of any Contractor’s employee requiring medical emergency treatment they will notify the Contractor’s trained 1st Aid person.
13.0 Work Sequence ( Steps to Complete the Task)
13.1 Mobilise to Site.
1. Bring all equipment and materials on to the site.
2. Ensure standby attendant is in position. All hoses are rolled out to minimise trip hazards.
3. Signage should be in place.
13.2 Stain removal of surface
1. Using soft washing equipment with good flow control, spray or brush the area to be cleaned with BENZ Blackwash in a concentration not greater than 5:1 ensuring no run-off of chemical into local drains. Block drains/gutters during application if necessary.
7/15/
2. Wait at least 30-60 minutes before rinsing the surface with suitable rinsing equipment such as a low pressure/high flow power washer, booster pump, or WFP (water fed pole).
3. Repeat the process until clean, bearing in mind
staining will fade dramatically once dry. Two applications are typical, three on only the most severe of cases.
Red staining, once turned pink, will disappear within 1-24 hours.
Black staining will turn a light brown and will mostly disappear with 24 hours. Some staining may still be present in the very worst of cases. This is probably water staining from the heavy biological growth and may improve with weathering over time.
8/15/
13.3 Treatment of surfaces
Now the heavy soiling has been removed from the surface, it may be treated with BENZ
Biocidal Wash to kill any organic spores that may remain. The active ingredient in BENZ
Biocidal Wash also has a latent affect and is able to penetrate deeper into the pores of the
surface than BENZ Blackwash. The concentration of BENZ Biocidal Wash can be as low as
50:1 in summer and 40:1 in winter
1. Use appropriate spray equipment and spray
techniques (WFP and BENZ Nozzle) to spray all
elevations, paying particular attention to areas
where algae and mould like to breed. These
places include capping stones, cement mortar
joints. window sills, and so on.
2. Work methodically to ensure saturation of the
entire surface, whilst at the same time keeping
run-off to drains to a minimum. Block
drains/gutters during application if necessary.
13.4 PPE ( Personal Protective Equipment) Required All spraying shall require the following PPE:
▪ Goggles ▪ Face visor that also covers the operators hair ▪ Chemical resistant gloves ▪ Respiratory Personal Equipment (RPE) – P3 ▪ Chemical spraying suit

Risk Assessment Method
1. Identify a hazard. Note this in the
assessment table.
2. Note the risk-effect of the hazard.
3. Add proposed controls-mitigation.
4. Select the category of potential
consequence with controls in
place. Use the table to the right
and note under ‘C’
5. Select the likelihood of the
occurrence taking place with the
current controls in place. Note this
under ‘L’
6. Determine risk category from risk
matrix. This will be a Roman
numeral. Note this under ‘RC’
7. Do not proceed with task if risk is
Category III or IV – use further
controls-mitigation to reduce risk to
a category I or II.
