CSCS Environmental Awareness 5

Question 1

What is a 'protected species' in the context of UK/US environmental construction law?

Accepted Answer

A plant or animal whose habitat and individuals are legally protected from harm or disturbance

Answer

Protected species (e.g., bats, certain salamanders, migratory birds) have legal protections that make it an offence to disturb them or their habitats without a licence.

Question 2

What does a 'brown field' site refer to in construction and environmental terms?

Accepted Answer

Previously developed land that may be contaminated and requires investigation before reuse

Answer

Brownfield land has previously been developed or industrially used and often requires contamination assessment and remediation before redevelopment.

Question 3

Which of the following best reduces dust pollution from earthworks on a construction site?

Accepted Answer

Applying water suppression to exposed surfaces and unpaved haul roads

Answer

Water suppression damps down exposed soil and haul roads, preventing fine particles from becoming airborne and affecting air quality off site.

Question 4

What is the environmental purpose of a 'wheel wash' at the exit of a construction site?

Accepted Answer

To prevent mud and sediment from being tracked onto public roads and into drainage systems

Answer

Wheel wash facilities remove mud from vehicle tyres before they leave site, preventing soil and sediment from entering public roads and drains.

Question 5

Why should tree root protection zones be established before construction begins near existing trees?

Accepted Answer

To prevent compaction and physical damage to roots that could kill the tree during construction

Answer

Root protection zones safeguard the critical root area from soil compaction and physical cutting, which can fatally damage or kill trees.
