Materials

Question 1

Material restriction
1. Precondition or Optimization
2. Intent
3. Issue
4. Solutions

Answer 1

1. Precondition
2. To reduce or eliminate human exposure to building materials known to be hazardous
3. Historical use of hazardous materials in construction such as asbestos, lead, and mercury have presented serious health effects. Exposure to these materials need to be limited.
4. Restrict asbestos, mercury, and lead in products utilized in the building.

Question 2

Interior hazardous materials management
1. Precondition or Optimization
2. Intent
3. Issue
4. Solutions

Answer 2

1. Precondition
2. Manage risks of human exposure to hazardous materials ubiquitously used in past construction practices.
3. Although these dangerous chemicals are now banned, they can still be found in established structures.
4. Existing buildings must be evaluated for the presence of of hazardous materials and evaluate their removal.

Question 3

CCA and lead management plan
1. Precondition or Optimization
2. Intent
3. Issue
4. Solutions

Answer 3

1. precondition
2. mitigate risks of human exposure to chromate copper arsenate and lead
3. in the 2000s CCA treated wood was restricted due to health concerns. Lead was typically used for paint on outdoor structures and may have contaminated the soil and surrounding ground.
4. Identify and remediate hazards associated with CCA and lead.

Question 4

Site Remediation
1. Precondition or Optimization
2. Intent
3. Issue
4. Solutions

Answer 4

1. Optimization
2. Promote the safer development of potentially contaminated sites by assessing and mitigating hazards
3. Contaminated soil associated with past industrial activities can leach toxic chemicals into nearby water and pose as hazards into indoor air systems. When left unmanaged contaminants from these sights can lead to health issues.
4. An environmental site assessment can reduce the risk of exposure to contaminated sites.

Question 5

enhanced material restrictions
1. precondition or optimization
2. intent
3. issue
4. solution

Answer 5

1. optimization
2. minimize exposure to certain chemicals by limiting their presence in products.
3. Newly introduced chemicals such has HSFs, PFCs, and orthophthalates have been proven unleathy to unborn children and pregnant women.
4. Select products that are devoid of such chemicals.
