Construction Hazards
 Ladders - Checklist in notes
 Consider ladder aides:-
Increase basal ‘area’
Increase support at top
Increase friction
 Other engineering aides
Hooks, eyes and ledges

Hierarchy of control will reduce their use

16/07/2015
11
Demolition Hazards
 Characterised by:-
lack of planning
minimal capital investment
disinterested clients
 Must consider mechanical means first
 Hand demolition generally only ‘soft strip’
 Recycling / land fill tas has helped
16/07/2015
12
Excavations
 Gravity and friction
 All ground it ‘good ground’ – to the worker
 All ground can be ‘bad ground’ - add water
 Support sides or remove sides – angle of repose
16/07/2015
13
Excavations
 From what depth? – crushed by trunk or above
 Don’t forget falls from height
 Other services / disturbance
 Other buildings or trenches
16/07/2015
14
Excavations – Types of Support
 ‘No’ support, benching and battering
 Sheet piles
 ‘Hit and miss’
 Trench / drag boxes
 Trench boxes
 Proprietary systems
16/07/2015

Confined Spaces
 Definition in notes
 Can be anywhere – not just holes / tanks
 Excavations
 ‘reasonably foreseeable specified risk’
 Plan - assessment

Confined Spaces
 Risk assessment
 Work prohibited (as per COSHH)
 Then hierarchy based
 Proper emergency plans – own (not 999)
 Training is essential

Contractors
 Anyone engaged in work on your behalf
 Perception of ‘no control’
 Octel case
 Issues are:
specification
competence
control

REGULATORY FRAMEWORK - HSE
KEY NATIONAL OBJECTIVE 2001/2002
Objectives:
i) To give priority to:
work where uncontrolled dry stripping is planned
(presumption of enforcement action);
new licence holders whose work has not been
previously inspected;
priority visits to those who have been sent warning
letter by ALU;
those whose licences are set to expire within next 4
- 6 months (if not visited during previous 12);
OBJECTIVES 2001 / 2002
those where local knowledge suggest they are not
performing to standard, but who have not had letter
from ALU;
ii) Ensure employees who have to wear RPE
have been face-fit tested;
iii) Reduce the unjustified use of power tools;
iv) Reduce unjustified work in hot environments.
ASBESTOS - the Problem
Between the 1950s and the 1970s, asbestos
was used extensively in the UK as a building
material
Over 1.5 million premises contain asbestos
Thousand of tonnes of asbestos still remain in
buildings
Over 3,000 people die each year from
asbestos-related diseases
ASBESTOS - the Problem (cont’d)
25% of people who are now dying from
asbestos-related diseases once worked in trades
associated with construction and building
maintenance (Peto et al, 1995)
Asbestos regulations were aimed at asbestos
removers and those working in asbestos
factories
We need to ensure that all people who could
come into contact with asbestos accidentally are
properly covered
HSC / HSE PROPOSALS
A new regulation in the Control of Asbestos at
Work Regulations 1987 (which would become
the Control of Asbestos at Work Regulations
2001)
A duty to manage the risks from asbestos
A new Approved Code of Practice to back up
the regulation and provide guidance to owners
of workplace buildings
WHAT WILL THE NEW REGULATION
REQUIRE?

Take reasonable steps to identify asbestos
materials in a building - either do a full survey,
assume all unknown materials contain
asbestos, or conclude that they can’t contain
asbestos (needs evidence);

Record the location and type of asbestos
materials identified;

Assess the condition of these materials;

Assess the risk they present;
WHAT WILL THE NEW REGULATION
REQUIRE? (cont’d)

Prepare a written action plan (to leave the
asbestos in place, to repair it or to remove it);

Inform others of the location and condition of
the asbestos-containing materials;

Carry out regular checks of the condition of
all asbestos-containing materials in buildings;

Review and revise the plan as necessary.
THE NEW DUTY
Who has the New Duty?
The person or body having control over the
situation giving rise to the risk in:

The workplace; and
 The common areas of rented housing
Extended to all social rented housing?
WHAT ARE THE OPTIONS?

Leave the asbestos in place and introduce a
management system (if the asbestos is in
good condition, unlikely to be damaged
accidentally and there are no plans for a
major refit or refurbishment);

Seal it or enclose it (if the condition of the
asbestos is not too bad);
WHAT ARE THE OPTIONS? (cont’d)

Remove it using licensed contractors where
necessary (if the asbestos is damaged, if it is
in poor condition, or if major work is planned
on the premises).
THE HEALTH & SAFETY (ENFORCING
AUTHORITY) REGULATIONS 1998

Schedule 2 lists activities allocated to HSE for
enforcement, regardless of the main activity;
 This includes construction work in a
“physically segregated area”;
 Almost all asbestos removal works fall to HSE
to enforce, regardless of type of premises;
THE HEALTH & SAFETY (ENFORCING
AUTHORITY) REGULATIONS 1998
(cont’d)

Proposed amendment will pass more work to
LA Inspectors relating to asbestos removal in
premises where they are the enforcers, eg
offices, shops, community centres,churches,
etc.
