Facility Siting Studies

Protecting Health, Safety, and Environment

At RedGuard, we’re known for safety, however, protecting lives and assets with our blast-resistant buildings is just one way we accomplish that. Facility Siting Studies, part of our Engineering Service offerings, can help you manage the risks associated with working in hazardous environments, and prevent accidents resulting in major financial loss, injuries, and lost lives. Facility siting studies are done to comply with regulations, meet industry guidelines and reduce the chances of public exposure. The OSHA 29 CFR Part 1910.119 Process Safety Management regulation (known as PSM) requires a facility siting study to be carried out in a company’s Process Hazard Analysis (PHA). Failure to conduct facility site studies could result in fines from OSHA, as well as trigger actions with more far-reaching consequences. All refineries, petrochemical or other chemical operations, and other facilities covered by the PSM regulation are required to complete facility site studies.

Hazard Analysis

A proper study will include a thorough assessment and offer mitigation solutions. We’ll give a clear analysis of potential hazards on your unique work site from explosions, fires and toxins. We’ll assess the damage that would be incurred by occupied buildings and the harm subjected to onsite personnel. Damage levels will be illustrated with overpressure maps of a calculated explosion. We’ll analyze the impact to onsite buildings, from both an exterior and interior point of view, plus, look at offsite areas and determine the response of each area to a blast.

Hazard Mitigation

RedGuard will provide guidance to reduce risk from explosion, fire and toxic hazards to personnel in buildings. Our analysis will include recommendations to reinforce existing buildings, replace them with blast-resistant buildings, or to determine if buildings should be relocated to areas less susceptible to damage.

A RedGuard Facility Siting Study Includes:

Occupied Building Assesment

Fire, Toxin, and Explosion Study

Temporary Building Siting

Permanent Building Siting

Blast Retrofit and Upgrade Design


Conceptual Design Studies and Final Retrofit Designs from RedGuard

As part of a company’s Process Hazard Analysis (PHA), their facility siting study may recommend that existing buildings be either moved, replaced or retrofitted. RedGuard’s Conceptual Design Study will present mitigation options for either reinforcing existing structures or replacing them. Additionally, a Final Retrofit Design will offer solutions that can be used to bring an existing facility into compliance.

Reasons to Retrofit a Building...or Not

Occupied buildings may not have enough blast capacity to resist the blast loads calculated in the explosion analysis studies such as facility siting, QRA, etc. Sometimes upgrades, or retrofits, can be made to existing structures so that the damage they sustain due to the blast load would be considered acceptable. Retrofitting a building may be a cost saving measure in terms of time and material, specifically when a building needs to retain a special purpose. For example, when a facility siting study shows that an existing control room building will sustain high damage or collapse when subjected to the blast load, sometimes a blast retrofit/upgrade can be performed in order to minimize, or eliminate, the need to update or move equipment, which could be a major cost factor.

Another consideration is the number of interruptions to day to day business. Careful consideration must be taken to determine if more time will be lost while a building is completely taken down and rebuilt, or while the building is offline during a retrofit. If a building contains critical infrastructure, replacement of the building could result in the entire plant requiring shutdown while it is replaced. A plant shutdown has major financial implications, so in this case, a building retrofit makes more sense.

When you work with RedGuard, you will get a turnkey set of plans to take to your contractor. The final retrofit design project will include a detailed cost estimate and construction documents, including plans and specifications.
