SAFETY GUIDELINES

To ensure this fieldtrip is safe and enjoyable, the following safety guidelinesshould be followed:

Wear a pair of sturdy, comfortable shoes (eg. walking boots, safety or

sports shoes);

Umbrellas and hats are recommended for protection from sun and/or

rain;

Outcrops are located along the busy trunk roads; thus, care should betaken to avoid accidents;

Avoid climbing steep quarry faces. Rocks tend to be easily dislodged

especially in the rainy season;

If you intend to collect rock samples with a hammer, wear safety glasses

or goggles and warn your neighbours before hammering the rock;

At the outcrops, beware of snakes, bees, scorpion etc.;

Be environmentally friendly; take your litter home.

If you have any other query, please ask the fieldtrip leaders.

Note: Have enough drinking water supply- it might be hot and you will

loose a lot of fluid.
