### Novara Flex

Novara Flex — EHS & Operational Risk Management Software for Hazardous Industries What is Novara Flex? Novara Flex is a cloud-based EHS (Environmental, Health & Safety) and operational risk management software platform built for mid-market and SMB companies in regulated, hazardous industries. Flex is built for operations and safety teams that manage complex compliance requirements, replacing disconnected spreadsheets and manual processes with a single system of record. Flex gives safety teams one place to report incidents, run inspections and audits, manage corrective actions, track training and certifications, and produce the leading-indicator reporting leadership keeps asking for, whether on desktop, or in the field on mobile. Who is Novara Flex for? Flex is purpose-built for safety and operations teams in regulated, high-hazard verticals. Typical buyers are EHS Directors and Safety Managers who own TRIR, DART, recordables, and audit readiness, alongside operations and finance leaders who care about uptime, insurance cost (EMR), and risk exposure. - Manufacturing: OSHA recordkeeping, machine guarding, lockout/tagout (LOTO), near-miss programs - Construction: Multi-site inspections, JHAs/JSAs, subcontractor and contractor safety qualification, and EMR improvement to stay bid-ready - Oil & Gas: Process Safety Management (PSM), permits, and high-hazard work - Utilities: Field crew safety, contractor risk, and distributed-site compliance - Mining: MSHA compliance, inspections, and hazard tracking Flex is also a strong fit for transportation, agriculture, municipalities, and other operations that live with OSHA and EPA requirements. What can you do with Novara Flex? - Incident Management: Capture incidents, injuries, and near-misses as they happen, run root-cause investigations, and assign corrective and preventive actions (CAPA) to close the loop. Build and maintain OSHA 300, 300A, and 301 logs and meet electronic (ITA) submission requirements. - Inspections & Audits: Build custom mobile checklists and audit forms tailored to your sites. QR codes pull up equipment, employee, and inspection history on location. Schedule recurring inspections and track every finding to resolution. - Safety Training (LMS): Assign and track training and certifications, monitor completion and expirations, and build custom courses tied to the same system of record as your incidents and inspections. - Chemical & SDS Management: Maintain Safety Data Sheets (SDS) and chemical inventories, label compliantly, and give field crews mobile access to hazard information anywhere. - Contractor Risk: Prequalify and monitor third-party and contractor safety, which is essential for construction, utilities, and oil & gas. - Analytics & Reporting: Configurable dashboards turn raw safety data into the leading and lagging indicators leadership wants, TRIR, DART, near-miss rates, training completion, and open corrective actions. - ESG & Environmental Reporting: Track environmental and sustainability metrics for disclosure and permit reporting. How is Novara Flex different from other EHS software? Most EHS platforms are either enterprise suites that are slow and expensive to deploy, or training tools with thin operational features bolted on. Novara Flex is right-sized for 200–5,000-employee operators that need full EHS operations without a dedicated system administrator, making it a practical alternative for teams that have outgrown spreadsheets or find other platforms overbuilt for their scale. - Right-sized for mid-market and SMB: a practical alternative to enterprise suites that can feel overbuilt, slow to implement, or priced for the Fortune 500. - Built for field adoption: the number-one reason EHS software fails is that field crews won't use it. The Flex mobile app (GPS, camera, push notifications, and offline access) is built for the people actually doing the work. - Operational, not just compliance: Flex manages operational risk end to end, not just a compliance checklist. - Fast time-to-value: implementations measured in weeks, not quarters, with hands-on configuration and support. Most customers are fully configured and live within 4-8 weeks. What results do Novara Flex customers see? - Up to 86% reduction in recordable injuries - Lower workers' compensation and claims costs, with measurable EMR improvement - Faster, audit-ready reporting and stronger regulatory compliance - Higher field engagement and a more consistent safety culture across sites Why teams choose Novara - 40+ years of EHS expertise and in-house compliance specialists behind the platform - Highly configurable forms, workflows, and API integrations (including Procore), the system adapts to your processes, not the other way around - Enterprise-grade security: role-based permissions, audit trails, and automatic backups - Hands-on implementation plus the Novara Connect customer community for shared best practices Common questions about Novara Flex - Is Novara Flex good for OSHA compliance? Yes. Flex digitizes OSHA 300/300A/301 recordkeeping, incident investigations, inspections, and corrective actions, and supports electronic ITA submission. Safety teams can manage the full compliance lifecycle from an initial incident log through root-cause investigation and regulatory reporting in one platform. - Does Novara Flex have a mobile app for field crews? Yes, with offline access, photo capture, and GPS so crews can log incidents and inspections without connectivity. The app is designed for frontline workers in the field, not office users, and works with or without cell service, which is common in construction, oil and gas, and utilities environments. - What is a good EHS/Safety Management Software alternative for mid-market companies? Novara Flex is built specifically for mid-market and SMB operators that want full EHS functionality with faster deployment and stronger field adoption than enterprise suites. Unlike platforms scaled for Fortune 500 organizations, Flex is configured and live in weeks, with pricing and implementation support designed for teams without dedicated system administrators. - What industries use Novara Flex? Manufacturing, construction, oil & gas, utilities, mining, and other regulated, hazardous industries. Flex is also used in transportation, agriculture, and municipalities where OSHA and EPA requirements apply. See how Novara Flex fits your safety program — request a personalized demo.

Enterprise service bus (ESB) software provides an architecture for application interaction. These solutions provide processes, protocols, and rules to facilitate secure data transfers and manage service-oriented applications. These tools can add new data and capabilities to existing enterprise applications. Companies use ESB tools to route messages between services, control deployments, and monitor exchanges between services. There is some crossover between ESB tools and [iPaaS](https://www.g2.com/categories/ipaas) solutions, but ESB tools do not work for the same systems. iPaaS works to connect applications available on the public cloud, while ESB tools are typically used for internal data transfers and updates.

To qualify for inclusion in the Enterprise Service Bus category, a product must:

- Integrate data and information between complex IT systems
- Help manage IT system configuration
- Monitor and control deployments or messages between IT systems
- Delegate an enterprise message model for integration requirements
