OSHA Compliance Software Built on Real Expertise Modern workplace safety demands more than basic checklists and generic templates. Effective exposure sampling programs require deep technical knowledge, strategic thinking, and decades of practical experience in the field. Our OSHA compliance software is founded on Master's-level training in industrial hygiene, with expertise spanning sampling strategy design, precision equipment selection, and rigorous data analysis protocols. This isn't software built by programmers alone—it's a platform developed by safety professionals who've spent years conducting real-world exposure assessments in complex industrial environments.
Equipment Selection: The Foundation of Accurate Sampling Respirable Dust Sampling Total Dust Collection Required for fine particles that penetrate deep into lung tissue, typically particles under 10 micrometers in diameter. Captures all airborne particulate matter regardless of particle size, used when the hazard exists across the full size spectrum. Applications include: Appropriate for: • Crystalline silica exposure assessment • Nuisance dust monitoring • Welding fume characterization • Lead exposure assessment • Coal dust monitoring • Pesticide application zones • Metal working fluid aerosols • Certain wood dust evaluations Requires cyclone separators or impactors to size-selectively capture only respirable particles. Uses open-face cassettes without size-selective devices, allowing collection of particles from sub-micron to visible sizes. Our software ensures you select the correct sampling methodology every time, preventing the costly error of using total dust methods when respirable monitoring is required—a mistake that can invalidate an entire sampling campaign and expose workers to unrecognized hazards.
Media Selection: Matching Method to Contaminant Particulate Filters Sorbent Tubes Passive Dosimeters PVC, MCE, or PTFE filters selected based on analytical method and chemical compatibility with the target contaminant. Charcoal, silica gel, or specialty media for vapor and gas collection—breakthrough volume is critical to prevent sample loss. Diffusion-based sampling for specific compounds when active sampling isn't feasible or when task-based monitoring is needed. Selecting the wrong media can lead to dramatic underestimation or overestimation of exposure. For example, using PVC filters for certain organic compounds can result in sample loss through volatilization, while using the wrong sorbent tube can allow chemicals to pass through uncaptured—a phenomenon called breakthrough. Our software guides you through media selection based on the specific chemical, expected concentration range, and sampling duration, reducing the risk of invalid samples that waste time, money, and compromise worker protection.
Data Analysis: Turning Numbers Into Protection Identify Additive Exposures Adjust for Extended Shifts When multiple chemicals affect the same target organ or system, exposures must be combined using the mixture formula: (C₁/PEL₁) + (C₂/PEL₂) + ... ≤ 1.0 OSHA PELs are based on 8-hour workdays and 40-hour weeks. Extended shifts require Brief & Scala or OSHA reduction factors to account for decreased recovery time. Apply Statistical Analysis Document Decisions Determine if the exposure profile represents acceptable control using 95% confidence intervals and comparing to action levels (typically 50% of PEL). Record the rationale for analytical choices, including why certain data sets were or weren't combined, and how shift length adjustments were calculated. Our OSHA compliance software automates these complex calculations while maintaining full transparency in the methodology. You'll never again wonder whether xylene and toluene exposures should be added together, or how to properly adjust a PEL when your facility runs 12-hour shifts. The system flags situations requiring professional judgment and provides the technical basis for decision-making.
Compliance Documentation Requirements 1 30 Years: Exposure Records Employee exposure monitoring data, including environmental and biological monitoring results, must be retained for the duration of employment plus 30 years per 29 CFR 1910.1020. 2 30 Years: Medical Records Medical surveillance results, including audiograms, respiratory fit testing, and exam reports for exposed employees, require the same extended retention period. 3 Duration of Use + 3 Years: Training Records Documentation of employee training on chemical hazards, PPE use, and exposure control methods must be maintained and made available upon request. 4 Duration of Use + 30 Years: Hazard Assessments For certain carcinogens and highly toxic materials, workplace hazard assessments and control measures must be documented and retained long-term. Failure to maintain proper documentation can result in significant OSHA citations, even if actual exposures were well-controlled. Our software automatically archives all required information with timestamp tracking, ensures nothing is inadvertently deleted before the retention period expires, and generates audit-ready reports that demonstrate your commitment to regulatory compliance and worker protection.
Empowering Your Team: In-House Expertise vs. Perpetual Consulting Build Internal Capability Relying exclusively on outside consultants creates dependency, delays decision-making, and increases long-term costs. While consultants provide valuable specialized expertise for complex situations, day-to-day hazard recognition and exposure control should be capabilities your team owns. Our software empowers your EHS team to: • Conduct routine exposure assessments independently • Make informed decisions about sampling strategy and timing • Recognize when situations exceed in-house capabilities and require external support • Maintain institutional knowledge even as team members change • Respond quickly to new hazards without waiting for consultant availability Think of it as providing your team with a technical advisor available 24/7, embedded in the software interface—guiding decisions, explaining regulations, and preventing common errors that even experienced professionals occasionally make.
Accuracy Through Technology: CAS Number Integration 30min 87% 146K+ Average Training Time Error Reduction Chemical Database Intuitive CAS# search reduces learning curve to approximately 30 minutes for experienced safety professionals Automated chemical identification eliminates documentation errors from manual entry and spelling variations Comprehensive library links CAS numbers to regulatory limits, hazard information, and sampling methods Chemical Abstract Service (CAS) numbers provide unique identifiers that eliminate confusion caused by trade names, synonyms, and regional naming variations. When you search by CAS# in our system, you instantly access the correct OSHA PEL, ACGIH TLV, NIOSH REL, sampling methodology references, health hazard information, and required PPE recommendations—all verified and linked to the specific chemical isomer or mixture you're evaluating.
Technical Papers: Bridging Science and Practice Understanding the "Why" Behind the "What" Workplace chemical hazards don't remain static. New processes introduce unfamiliar materials, regulations evolve, and research reveals previously unknown risks. Your team needs access to authoritative technical information that explains not just what to do, but why it matters. Our platform includes a library of technical papers written at what we call "science-geek level detail"—rigorous enough to satisfy a Certified Industrial Hygienist, yet translated into language that safety professionals without advanced degrees can understand and apply. Topics include: • Sampling strategy development for specific industries • Interpreting analytical laboratory reports • Understanding detection limits and their impact on exposure decisions • Emerging contaminants and updated exposure guidelines • Ventilation effectiveness evaluation techniques These resources help your team think critically about exposure scenarios rather than simply following rote procedures—developing the judgment that separates competent compliance from true expertise in protecting worker health.
Decoding Exposure Limits: STELs, Ceilings, and TWAs Time-Weighted Average (TWA) Short-Term Exposure Limit (STEL) Ceiling Limit (C) Concentration that must never be exceeded at any time, even instantaneously. Requires real-time or grab sampling to verify compliance. The average concentration over an 8-hour workday—the most common exposure limit type. Allows for short-term peaks above the limit if balanced by periods below. Maximum concentration for a 15-minute exposure period. No more than four STEL exposures per day, with at least 60 minutes between exposures. Example: OSHA PEL-C for formaldehyde = 2 ppm ceiling limit Example: OSHA PEL for toluene = 200 ppm as an 8-hour TWA Example: ACGIH TLV-STEL for toluene = 150 ppm for 15 minutes Understanding which limit applies and when is critical for exposure assessment design. You can't use 8-hour TWA sampling to evaluate a ceiling limit—different limits require different sampling strategies. Our software identifies which limits apply to each chemical in your workplace and ensures your sampling approach matches the regulatory requirement. The system also flags situations where multiple limits exist (such as both a TWA and a STEL) so you don't inadvertently miss a required exposure evaluation.
Mastering OSHA Regulations: Knowledge That Protects Read Regulations Effectively Identify Applicable Standards Determine Real-World Impact Learn to navigate the structure of OSHA standards, understanding how general industry (1910) differs from construction (1926), and how to find applicable requirements in the Code of Federal Regulations. Determine which OSHA standards apply to your specific workplace based on industry classification, processes used, and materials present—some facilities must comply with dozens of substance-specific standards. Understand what actually applies to your operations versus what appears relevant but has exemptions, exceptions, or applicability criteria your workplace doesn't meet. OSHA regulations can be intimidating—dense legal language, cross-references between sections, and substance-specific standards that each have unique requirements. Our software includes interpretive guidance that helps you understand not just what the regulation says, but what it means for your workplace. Built-in compliance assessments ask targeted questions about your operations and generate customized requirement lists showing exactly which OSHA provisions apply and which don't. This eliminates the common problem of either over-compliance (implementing requirements that don't apply, wasting resources) or under-compliance (missing applicable requirements and creating citation risk). You'll develop confidence in reading regulations directly, knowing when professional interpretation is needed, and making informed decisions about workplace safety investments that truly protect your employees.
