The construction industry has been trying to improve safety and security around the country, but the Federal Aviation Administration is warning that safety standards in the construction sector are not up to scratch.

The FAA issued a bulletin to its employees Friday urging them to be vigilant, particularly for people working in the vicinity of airports.

The bulletin cites several safety issues, including the spread of dangerous materials at construction sites, including cement, concrete, asbestos, and other toxic materials.

It also cites construction sites as the potential site of an emergency, warning that “an air traveler who arrives at a construction site at night, is unaware of the safety measures in place, and does not take adequate precautions may be exposed to hazardous materials.”

The FAA also warns that contractors who are not responsible for maintaining and monitoring their sites, such as construction sites operators, should be held responsible for any safety issues they cause.

The aviation industry has long struggled with the problem of building sites being unsafe.

Some companies have even moved out of the United States to avoid liability.

The agency also advises that contractors and others who have a duty to maintain the sites, which are open to the public, should also follow those safety guidelines.

Construction safety issuesThe FAA has a lot of work to do on its construction safety website, but it also has some other safety issues to deal with.

For example, it says that some contractors do not have written policies or procedures that are clear, detailed and enforceable.

In some cases, the safety rules have not been clearly spelled out or even enforced, which can make it difficult for people to report safety violations.

The safety rules also don’t include clear penalties for violations.

That can be a real challenge for contractors, especially if they are small companies with little resources and don’t have a large workforce.

The government should also create a system for workers who may not be aware of the construction safety rules to report violations, said David Gifford, president of the Association of Contractors of America.

Gifford says that there is a real risk that employers could use the FAA’s rules as a tool to try to intimidate workers and reduce their bargaining power.

The Safety and Security Act of 1979, passed after the Sept. 11, 2001 terrorist attacks, requires the FAA to develop safety and enforcement guidelines for all federal contractors and subcontractors.

It also requires contractors to develop a program to monitor the safety of construction sites.

Federal safety standards are not perfect, but they are better than what we have in the past, Giffart said.

The National Transportation Safety Board, a federal agency, oversees the FAA.

The FAA did not respond to a request for comment.
