Construction, Special Event and Hospital Security Guards


  • Construction site and warehouse security guards

Construction sites and warehouses are a common target for night time break-ins since there is usually no one around to ward of vandalism, property damage or keep an eye on expensive materials and machinery. Our overnight security guards are highly trained, equipped with the latest training and technology and in direct contact with our award-winning dispatch team.

  • Indoor and outdoor special event security

With experience providing security for indoor and outdoor venues, our special events security guards can handle everything from crowd control and parking enforcement to patron removal. Armed and unarmed security guards are available for special event assignments, as well as plain clothes or uniformed officers.

  • Health care facility security guards

Maintaining the safety of our local hospitals and clinics is among the most important jobs we have at First Security Services. Our medical facilities security guards work with your staff to address any existing safety issue, and to deter any potential issue.
