Chemical Hazard Use Application (CHUA)

Learn how to use the Hazard Control Plan Application.

The Hazard Control Plan Application is a Web-based tool provisioned with Hazard Control Plans (HCPs) for work with hazardous chemicals, equipment, or processes. At UC San Diego a hazard control plan is a standard operating procedure.

Requirement for researchers

UC San Diego requires investigators to log into the Hazard Control Plan Application to create HCPs for work with hazardous chemicals, equipment, and processes.

Principal Investigators will use this application to:

  • Determine what HCPs are required in their laboratories and then adopt those HCPs.
  • Provide detailed instructions on how to safely work with the chemicals, equipment, or processes.
  • Assign lab personnel to each Hazard Control Plan.
  • Serve as the repository for all of their HCPs.

CHUA's Hazard Control Plan templates

Hazard Control Plan (HCP) templates are essentially safety SOPS and are available for all chemical hazards as well as various pieces of equipment and laboratory processes. These templates are drafted by EH&S safety professionals and are vetted either by researchers, or other EH&S safety professionals for accuracy and applicability.

Principal Investigators are required to adopt these templates for everything that applies to their research and are responsible for ensuring their lab-specific HCP will provide a safe working environment. For help in drafting your HCP review the Hazard Control Plan Resources page.

Every template has core template language in various sections throughout the document. These core template sections are uneditable and must not be modified or weakened by research staff in their finished documents. In every template there are links to other resources that must be followed.

Core HCP template sections:

  • Opening header.
  • The name of the template. This section contains general information about the chemical, equipment or process.
  • Required Training/Approvals. This section contains specific training and approval requirements.
  • Administrative Controls. This section contains critical administrative controls to help manage or eliminate the risk prior to performing research activity.
  • Engineering Controls. This section contains important measures you need to take to manage the risks of possible exposure prior to performing research activity.
  • Personal Protective Equipment. This section describes what personal protective equipment (PPE) is required to safely perform your research activity.
  • Handling/Storage/Purchasing. This section describes important measures that need to take place in the laboratory to ensure the safety of research staff.
  • Spill Response. This section describes what do in the event of a spill.
  • Exposure Response. This section describes what to do in the event of an exposure or injury.
  • Hazardous Waste Disposal. This section will help you manage the hazardous waste aspects of your research.
  • References and Resources. This section provides some useful references and resources for this specific hazard control plan.

Each adopted template also contains two editable fields that are for the labs to complete. These fields must be completed before the PI can approve the HCP.

Editable sections

  • Summary section. A short summary on why or how you are using this material, equipment, or process.
  • Lab Specific Instruction section. Provide detailed instructions on how to safely work with the chemicals, equipment, or processes. Consider the following when populating this field: quantities, concentrations, conditions of use, unusual or dangerous characteristics, PI restrictions, where it will be used, scale-up restrictions and physical process highlights such as heating, pressure, cooling, etc. It is the PIs responsibility to provide sufficient instructions in each HCP to ensure safe research activity within their lab.

There are two categories of Hazard Control Plan templates – CSSC Approved and EHS Reviewed: This distinction is not an important feature to the researcher but simply clarifies the two types of HCPs.

  1. CSSC Approved Hazard Control Plans

These templates are approved by UC San Diego's Chemical Safety & Surveillance Committee (CSSC) for work with materials identified as high hazard chemicals. If your lab uses any of these chemicals then you are required to use the chemical specific Hazard Control Plan. Ex: Arsine, phosphine, trfluoroacetic acid, sodium cyanide etc. See the "High Hazard Chemical List" below.

  1. EH&S Reviewed Hazard Control Plans

These are Hazard Control Plan templates for work with thousands of other hazardous chemicals, equipment, and processes. The chemicals are grouped by hazard classification. Ex:  Pyrophoric, Strong Corrosives, Water Reactive Materials, Acutely Toxic Materials etc.

Create a Hazard Control Plan

Create a new HCP in My Research Safety:
  1. Click the My HCP tab. 
  2. Click the Create HCP button. 
  3. Choose the Principal Investigator  from the drop down.
  4. Use the CSSC HCP Chemical List drop-down menu and select a chemical. (Note: A Hazard Control Plan cannot be created for a chemical that is already on the CSSC HCP Chemical List.) 
  5. Click the Create button.
  6. Hazardous Material – Step 1 allows you to add chemicals you will be working within your HCP. Use the Search box to locate the chemical(s) you will be working with, tick the chemical once you find it and click Add Chemical to HCP. (If your HCP is already a chemical and you will not be using any other chemicals, skip this step.) You can add comments and instructions in the Lab Instructions box next to your selected chemical by typing and clicking Update. Click the arrow to go forward to Step 2.
  7. Project Summary/Lab Specific Instructions – Step 2 contains two lab responsible fields. In the Project Summary box, provide a short summary of how the material(s) will be used. Include the names of the chemicals and a short abstract of the project (1 or 2 sentences). In the Lab Specific Instructions box provide detailed instructions about how this material will be used. Consider the following when populating this field: quantities, concentrations, conditions of use, unusual or dangerous characteristics, PI restrictions, where it will be used, scale-up restrictions and physical process highlights such as heating, pressure, cooling, etc. Click Save when finished. 
  8. Hazard Control Plan – Step 3 cannot be edited and is meant to be for instructional purposes only.
  9. HCP Lab Personnel – Step 4 Allows lab personnel to be added to the Hazard Control Plan. Use the Select Lab Personnel link to add lab employees and then utilize the Email HCP to recipient button at the bottom to send an e-mail notification of their HCP assignment.
  10. HCP Submittal – In Step 5, only the PI can submit a Hazard Control Plan and should do so promptly upon completion. Click Approve HCP

Tag out chemicals not in use

"Tag out" chemicals to keep them in inventory for future use without having to write a SOP/HCP by attaching a SOP Required sticker (PDF) to the container.

The SOP Required sticker signifies the chemical is "tagged out" and may not be used by anyone until these conditions are met:

  1. A Hazard Control Plan has been generated
  2. Research staff have been assigned to the Hazard Control Plan
  3. All individuals comply with and sign off on all aspects of the Hazard Control Plan prior to its use
  4. The PI approves and signs the Hazard Control Plan

Contact the Research Assistance Program specialist assigned to your area to request a supply of "SOP Required" stickers.

Regulations and policies

Guiding principles

(From Prudent Practices in the Laboratory)

The OSHA Laboratory Standard (29CFR 1910.1450) breeds a culture of safety consciousness, accountability, organization and education.

All faculty and research supervisors should note that a vital component of science/chemical education is teaching students how to identify the risks and hazards in a laboratory. Such education serves scientists well, and places them at a professional advantage, in their ultimate careers in government, industry, academe, and the health sciences.

Hazard Control Plans incorporate risk assessments, planning, and step-by-step safety protocols, which are all as much a part of scientific education as learning the theoretical background of an experiment. Nurturing basic attitudes and habits of prudent behavior is crucial so that safety is valued and becomes an internalized attitude, not just an external expectation driven by institutional rules.
