Occupational Health & Hygiene
VO Multi Solution provides services for Industrial Hygiene practices and standards that are designed to keep the work environment sanitary and safe for your workers and for the adjacent community.
Recognizing workplace hazards can be challenging, and implementing engineering, administrative, and personal protective equipment controls to address these hazards can be a daunting task. That is where the science of Industrial Hygiene can help. Industrial Hygiene is devoted to anticipating, recognizing, evaluating, preventing, and controlling environmental factors and stresses present in the workplace. These factors and stresses have the ability to cause sickness, impair health and well being, or cause discomfort among workers and the general public.
We of board certified industrial hygienists and environment specialist can work with you to find cost effective solutions to protect your employees, increase productivity, minimize environmental impacts, and reduce business risks/interruptions.

Real World Applications
The following summary outlines the preliminary activities and foundational tasks completed
Site
At Savannakhet, Lomakham Drinking Water
The primary objective of this visit is to conduct an annual external supplier audit for Lomakam Drinking Water in Savannakhet, ensuring their operational processes strictly adhere to our corporate compliance standards and safety protocols.
Site
Vilabouly District, Raw fish, and pork local suppliers
We conducted our Half-Year Food Hygiene Audit—a systematic, independent examination of food handling practices—with our local Raw Food Suppliers. This audit ensures that both the Preparation (the processing and handling of raw materials) and Transportation (the temperature-controlled logistics chain) are in full Compliance with our company’s internal safety policies and international food safety standards.
Site
Sepon Site, Catering Area
We performed random weekly inspections of ready-to-eat catering materials and beverage containers using 3M Bacterial Surface Instant Testing—a rapid hygiene monitoring system that detects Adenosine Triphosphate (ATP), the energy molecule found in all organic matter. This process ensures that all food-contact surfaces have been sanitized and cleared of bacterial loads in strict accordance with our Standard Operating Procedures (SOPs).
Site
Vientiane Capital, external frozen products supplier
We conducted an Annual Food Hygiene Audit—a systematic evaluation of food safety practices throughout the supply chain—in collaboration with Vientiane-based stakeholders. This audit encompasses both raw material and processed food suppliers to verify that their preparation protocols and transportation logistics are in full compliance with our company’s Internal Quality Standards (IQS) and local health regulations.
Site
Sepon Site, Copper Processing Plant
We initiated the Noise Mapping Project—This mapping allows us to identify 'Red Zones,' where Hearing Protection Devices (HPDs) are mandatory, versus 'Green Zones,' where protection is not required. These designations remain static unless a significant change in equipment, layout, or activity levels triggers a shift in the acoustic profile, necessitating a re-mapping of the site.
Site
Sepon Site, New Extension Gold Plant Project
We conducted Mercury Vapor Indicating (MVI)—a real-time monitoring process used to detect and quantify mercury concentrations in the air—to ensure all construction personnel were operating within a safe Health, Safety, and Environment (HSE) framework.
Site
Sepon Site, Oxygen Plant
We evaluate Noise Exposure and Vibration. By defining the Noise Reduction Rating (NRR) required for the environment and mapping 'Noise Zones,' we determined the specific time-compliance boundaries. This allows personnel to understand the exact duration they can safely operate in the plant before hearing protection becomes a mandatory requirement under HSE regulations.
Site
Sepon Site, Copper Plant
We conducted weekly gases monitoring - a real-time monitoring process used to detect and quantify CO2, SO2 concentrations in the air—to ensure all personnel were operating within a safe Health, Safety, and Environment (HSE) framework.
Site
Sepon Site, Gold Plant Operators
We implemented Hearing Fit Testing—a diagnostic method that measures the 'Real-Ear Attenuation at Threshold' for an individual—to ensure that workers in High-Risk Similar Exposure Groups (SEGs) are utilizing their hearing protective equipment correctly. This validation is critical to confirming that the actual noise reduction matches the equipment’s rating.
Site
Sepon Site, Engineering Techniciansect
We delivered Asbestos Awareness Training—a specialized educational program designed to help personnel identify, avoid, and report materials containing asbestos—to ensure that all operators handle hazardous substances safely. This training emphasizes the correct selection and fit of Respiratory Protective Equipment (RPE),
Site
Sepon Site, Laboratory Technicians
We conducted individualized Respiratory Fit Testing—a standardized protocol used to evaluate the seal between a respirator's facepiece and the wearer’s face—to ensure each operator is equipped with the correct size and model. This one-on-one session is essential to verify that the equipment provides an adequate Assigned Protection Factor (APF),
Site
Sepon Site, Project Technicians
We conducted Weekly OHS Awareness sessions—systematic briefings designed to reinforce workplace safety protocols—with identified operators to provide a dedicated forum for identifying concerns regarding Personal Protective Equipment (PPE) or broader Occupational Health and Safety (OHS) standards. This ensures that any potential hazards are reported and mitigated in real-time.
Site
Sepon Site, Gold Plant Operators
We implemented Hearing Fit Testing—a diagnostic method that measures the 'Real-Ear Attenuation at Threshold' for an individual—to ensure that workers in High-Risk Similar Exposure Groups (SEGs) are utilizing their hearing protective equipment correctly. This validation is critical to confirming that the actual noise reduction matches the equipment’s rating.
Site
Sepon Site, mining pits
To proactively manage industrial health risks, the team performed Real-time Ad Hoc Monitoring of Asbestos and Respirable Crystalline Silica (RCS). This process involves the continuous measurement of particulate mass concentrations in the worker's breathing zone, allowing us to identify 'peak' exposure events during specific tasks. These data points are essential for understanding how to minimize risk through the Hierarchy of Controls, such as high-efficiency particulate air (HEPA) filtration and wet-cutting methods.
Site
ROM Pad
We set up portable PM2.5 and PM10 monitors at the ROM Pad to prevent particulate matter (PM) exposure for operators working downwind at the copper and gold plants.
Site
Residence Camp
We are conducting environmental noise monitoring at the boundary between the residence camp and the oxygen plant. This ensures noise levels remain within permissible limits to safeguard operator sleep quality and mitigate fatigue-related risks.
