24-HOUR Dispatched Service

ON-SITE HEALTH & SAFETY is a 24-hour provider of essential health and safety services. Certain services can be better performed at the worksite, instead of an off-site facility.

Here’s how it works!

Set Up A Protocol

In just a brief, five-minute phone consultation, we gather all the information necessary to get your company set up to receive the services you need, and what protocols you wish to have followed. From post-accident drug screens, breath alcohol testing, and respiratory services to getting dialed in to receive our industry-leading, 24-hour mobile first aid response…On-Site has your health and safety needs covered.

You Call For Service

Pre-scheduled or dispatched…we go when and where you need us, 24-hours a day, seven days a week.

On-Site Dispatcher Takes Call

Our trained and friendly dispatchers are standing by to take each and every call…24-hours a day. After a brief triage of the situation to quickly assess the urgency of each call, dispatch quickly locates the On-Site field tech nearest to you.

Field Tech Is Dispatched

Strategically placed…our technicians respond promptly to each call received.

Field Tech Arrives at Worksite

Dawning mobile gear and supplies while dressed in the same attire you would typically see of the EMT’s and Paramedics we employ, our technicians are not only highly trained…they also look the part of the professional provider you would expect from today’s industry leader.

Field Tech Provides Requested Service

With 24-hour prompt response provided right at your worksite, an On-Site field tech arrives to handle everything you need. From respirator fit tests to handling incidents with non-life threatening injuries…we’re here to help when you need us the most.

Field Tech Completes Required Paperwork

As part of your protocol and our compliant process, our technicians complete the necessary paperwork for each of the services we offer. All paperwork is reviewed by our QA/QC department and securely sent to the point of contact previously established by your company.

You Receive Copies of The Paperwork

Completed with efficiency and sent out in a timely manner, your company then receives all the required paperwork to satisfy your record keeping processes.

I first worked with On-Site Health and Safety while working in construction safety for a large mechanical contractor, yet recently made the move into retail, becoming the Corporate Risk Manager for WSS Shoe Stores.

On-Site’s services are the foundation to our post incident response. They’re the first call we make in non-life threatening events. The training services they offer are a complement to our already very extensive in house training programs. On-Site picks up what we miss or we use them to add to what we already have. Thanks for being there all these ... more

On-Site’s staff and technicians are professional, courteous, and knowledgeable, and response times are always within an hour. All of our cases to date have remained First Aids, costs have been kept low, and the negative effects of the injuries (time wasted sitting at a clinic, loss of productivity, adverse impact on incident rate) have been kept to a minimum.

ESSE Construction Safety Support, LLC
Their First Aid response saved us thousands of dollars in costs. When a worker received a small cut, something in his/her eyes, small burns, or even contusions, small strains, and sprains, On-Site would respond within an hour to the job site where the individual was injured. 99% of the time, the injury would remain a first aid case.
