Ask the right exposure question. Collect useful information.
MRA Consulting LLC helps employers evaluate workplace exposure concerns and plan appropriate follow-up. Services can include exposure assessment, air and noise monitoring, and respiratory protection or hearing conservation program support, with qualified specialists and laboratories coordinated where the project requires them.
A monitoring result needs workplace context
A monitoring result needs
workplace context
The first question is not simply which test to order. It is what employees may be exposed to, during which tasks, for how long, and under what conditions. We help define the assessment so the information collected supports a meaningful decision.
Exposure assessment planning
Review tasks, materials, safety data sheets, existing controls, employee concerns, and available exposure records. Identify questions, affected work groups, and the information needed to plan monitoring or further assessment.
Air monitoring support
Scope task-based or employee exposure monitoring around the contaminants and work being evaluated. Sampling methods, equipment, laboratory analysis, and technical review are selected for the assessment objective rather than a generic test package.
Noise assessment and monitoring
Review noise-producing activities and plan area measurements or personal dosimetry as appropriate. Help relate the findings to employee work patterns, applicable requirements, and potential hearing conservation follow-up.
Controls and program improvements
Help evaluate practical exposure-control options and identify related training, respiratory protection, or hearing conservation needs. Specialist design, clinical services, and additional testing are identified separately when required.
What you receive
Depending on the agreed scope, your package may include:
- An assessment or sampling plan
- Measurement results
- Interpretation against identified criteria
- Field observations
- Laboratory reports, where applicable
- Recommended next steps
Reports explain the work conditions evaluated, limitations, and any need for further sampling or specialist review.
When this service
is a good fit
Use this service when employees work around dusts, fumes, vapors, or elevated noise; when materials, ventilation, or production change; or when existing measurements do not answer your exposure question. We help identify what to evaluate and whether monitoring is appropriate.
How the engagement works
Define the right assessment
before ordering the test
Share the material or noise concern, work activity, existing results, and facility location. MRA will help scope the next step and any specialist support needed.
Frequently asked questions
Not necessarily. Area readings describe conditions at a location, while personal sampling or dosimetry can assess exposure during an employee’s work. The method must fit the question; a general area reading should not automatically be treated as proof of personal exposure compliance.
No. Results apply to the conditions and period evaluated. Different tasks, materials, production levels, ventilation, or work practices can change exposure. Reports should explain what the assessment does—and does not—establish.
Clinical medical evaluations and diagnoses are separate services performed by appropriate healthcare professionals. Employees required to use respirators need a medical evaluation before fit testing or use. Required use of tight-fitting respirators also requires fit testing. These activities are separate from exposure monitoring.
