2.4 GUIDELINES FOR THE DISPOSAL

OF SCRAP PRODUCTS

When it has been identified that a turf care

product has no further functional value and

requires disposal, the following actions

should be taken.

These guidelines should be used in

conjunction with applicable Health, Safety

and Environmental legislation and use of

approved local facilities for waste disposal

and recycling.

 Position the machine in a suitable

location for any necessary lifting

equipment to be used.

 Use appropriate tools and Personal

Protective Equipment (PPE) and

take guidance from the technical

manuals applicable to the machine.

 Remove and store appropriately:

1. Batteries

2. Fuel residue

. Engine coolant

4. Oils

 Disassemble the structure of the

machine referring to the technical

manuals where appropriate.

Special attention should be made

for dealing with stored energy

within pressurised elements of the

machine or tensioned springs.

 Any items that still have a useful

service life as second hand

components or can be re-serviced

should be separated and returned

to the relevant centre.

 Other worn out items should be

separated into material groups for

recycling and disposal consistent

with available facilities. More

common separation types are as

follows:

o Steel

o Non ferrous metals

 Aluminium

 Brass

 Copper

o Plastics

 Identifiable

 Recyclable

 Non recyclable

 Not identified

o Rubber

 Items that cannot be separated

economically into different material

groups should be added to the

General waste area.

 Do not incinerate waste.

Finally update machinery records to indicate

that the machine has been taken out of

service and scrapped.

on and off the roads. Keep alert and

aware at all times. Watch out for traffic

when crossing or near roadways.

 Stop the blades rotating before crossing

surfaces other than grass.

 Remember that some people are deaf

or blind and that children and animals

can be unpredictable.

 Keep travelling speeds low enough for

an emergency stop to be effective and

safe at all times, in any conditions.

 Remove or avoid obstructions in the

area to be cut, thus reducing the

possibility of injury to yourself and/or

bystanders.

 When reversing, take special care to

ensure that the area behind is clear of

obstructions and/or bystanders. DO

OT carry passengers.

 Keep in mind that the operator or user is

responsible for accidents or hazards

occurring to other people or their
