Staying Compliant to Meet Corporate Goals

Steve Delmar is a senior leader at Exide Technologies, a multinational lead-acid battery manufacturing company that must comply with strict regulatory policies.

The Georgia-based company recently completed a lead abatement project on the West Coast.

All of the associated abatement work must be conducted in air-tight enclosures that require constant air pressure differential monitoring. Negative pressure must be maintained within the enclosure to ensure lead containing dust is not released into the environment.

The U.S. Department of Labor has published detailed guidelines on the acceptable levels of lead particles permitted in the air during a typical workday.

The DoL says: The permissible exposure limit (PEL) of 50 micrograms of lead per cubic meter of air (50 μg/m3), averaged over an 8-hour workday which is referred to as a time-weighted average (TWA).

This is the highest level of lead in air to which you may be permissibly exposed over an eight-hour workday.

The Labor Department as well as OSHA and local workplace regulators regularly levy significant fines to businesses that fail to operate within these specific standards.

Sonicu works with many customers similar to Exide to help them stay on the right side of regulators while keeping their employees safe with automated monitoring and compliance reports.

Keeping OSHA Satisfied: Simple Audit Reporting

Exide is working on a lead abatement project at a shuttered recycling facility in California.

To accommodate this project, all abatement work was conducted in air-tight enclosures that require constant pressure differential monitoring.  

Moving the sensors and probes from different locations required occasional support from Sonicu technical staff. Sonicu also helped Exide produce tailored reporting for their industry and regulators. 

“Sonicu support has been great to work with for implementation, training, and helping to customize their standard reports to meet our unique requirements,” Delmar said.

Exide required a system that could provide continuous pressure data to a local operator working on the site, as well as send data remotely and in real-time to operators and management in various and often shifting locations.

Sonicu’s alarm system will notify anyone when air pressure differential levels experience an excursion outside of required specifications.

With air quality management rules enforced by local and federal air quality officials, Exide has to meet a diverse array of regulation standards that normally require time-consuming data management.

Exide needed to report data that was monitored every 15 minutes to determine a 15-minute average and to demonstrate compliance to agencies such as Occupational Safety and Health Administration (OSHA) which regulate and enforce lead particles in the air at worksites.


OSHA regulators regularly conduct surprise inspections at worksites to test for potential violations like lead particles in the air. Sonicu helps firms like Exide avoid stiff penalties and the headache of proof of compliance with our remote wireless air pressure differential monitoring to ensure their lead abatement work remains compliant.

Exide's goal is to keep lead dust from being emitted into the environment resulting in toxic air and significant fines.

Lead released into the environment has a toxic impact on humans and ecosystems.

According to the Environmental Protection Agency, depending on the level of exposure, lead can adversely affect the nervous system, kidney function, immune system, reproductive and developmental systems and the cardiovascular system.

Anyone who’s bought an older home knows how inspectors check for evidence of lead-based paint.

Lead can also be deposited into soils and sediments through deposition from lead air pollution.

Other sources of lead to ecosystems include direct discharge of waste streams to bodies of water and mining.

Elevated lead in the environment can result in decreased growth and reproduction in plants and animals, and neurological effects in vertebrates, including people. 

In short, lead is a serious threat, and regulators don’t look kindly upon firms not taking every precaution to control its release and spread into our environment.

Portable and Affordable: A Monitoring Solution That Moves with You

Sonicu's air pressure differential monitoring systems allow Exide to meet all set regulations and receive the data they need to help avoid penalties.

Steve Delmar, Environmental Health & Safety Manager at Exide, stressed the ability to move pressure sensors from one location to another as project conditions changed.

This allowed Delmar to save money by not having to invest in separate monitoring kits for each worksite.

Having remote, wireless sensors that can be quickly and easily transported from one location to another was an important reason we selected Sonicu for this job, Delmar said.

When you complement the simple moving of the hardware with the simplicity and mobility of the mobile app, Sonicu delivers a powerful solution for the professional on the go. 


Flexible, Affordable and Cloud-Based Monitoring

The Sonicu wireless ARC 440 digital meters, with integrated local display connected to Sonicu digital air pressure differential sensors, provide a real-time data view of pressure relationships.

Continuous data view allows operators to check all sensors as needed.

Sonicu meters transmit all data via Wi-Fi to the SoniCloud platform for 24/7 remote access via desktop or the Sonicu mobile app.

The 24/7 access Sonicu monitoring platform also provided an tiered alert system that reports to the appropriate operators and management personnel.

SoniCloud auto-generated reporting feature enables Exide to receive daily reports for full situational awareness and regulatory compliance.

Sonicu’s automated remote air pressure monitoring system allows for Hospitals, Pharmaceutical, Construction, and HVAC Systems to monitor working conditions and decrease unsafe working conditions. Sonicu’s monitoring automatically documents room pressure and records it in the cloud, eliminating manual processes and automating regulator audit reports to streamline compliance reporting. Sonicu allows 24/7 monitoring access and advanced alarms.

A Safer and More Compliant Facility

Exide’s complying with local and national regulations was once a cumbersome and tedious burden on Exide employees that required regular manual logging and detailed reporting.

Now, with Sonicu's air pressure differential sensors tied to the simple reporting platform, compliance is easily verified in a few clicks.

Local meters capture pressure reading in real-time, allowing Exide operators and management to access and view pressure readings 24/7 on SoniCloud from any tablet, smartphone, or personal computer and take action in real-time to protect staff and the environment. 

Daily reports from Exide are generated in SoniCloud and emailed to appropriate users in the system to perform regulatory compliance.

Exide’s requirement to be able to move the monitoring and transmission kit from one location to another allowed greater flexibility and saved money by avoiding additional kits.

“Sonicu air pressure differential equipment can be easily moved from one location to another to provide a client like Exide the flexibility it needs to get the job done safely without the expense of more kits,” said Joe Mundell, Chief Revenue Officer of Sonicu.

Exide Technology has set core values that are committed to protecting the health and safety and well being of employees.

Exide has set three sustainability goals they aim to achieve:

Sonicu helps Exide meet these goals with our 24/7 monitoring and automated regulatory audit reports streamlined.

According to Exide website, all manufacturing and recycling plants operate under a formal Environmental Health and Safety Management System (EHSMS) as well as Quality Management Systems (QMS), which includes permitting and licensing schemes and management of various legal and other requirements.

Monitoring and management of various key performance indicators (KPIs) ensures effective control of aquatic and atmospheric emissions and waste.

In addition, the company has implemented Management Systems approach that conforms to ISO requirements and is included in the scope of our stringent internal auditing scheme.

Exide’s Quality and EHS Management System has been satisfactorily demonstrated to external ISO certifying bodies with Exide’s manufacturing locations globally being certified to ISO 9001, IATF 16949 (when relevant), ISO 14001, ISO 50001, ISO 45001 or a combination of them.
