Safety In crude oil tanker operations, the hazards associated with H2


can be more severe than for bunkering. Section 1.4.6.2 of the ISGOTT Guide reminds crews that a crude oil with 80ppm by weight can yield 7,000 ppm by volume of H2


leaving the tank vent. The occupational exposure limit for H2 S is 20ppm by volume.

However, the alarm on a portable gas detection unit would generally be set at half of this level. The human nose can detect H2

Understanding the risks of H2 S during bunkering and crude transportation


Safety guidance on bunkering operations is provided in the ISGOTT Sith Edition in chapter 24. Most ships use marine fuel oil or heavy fuel oil as their propulsion fuel. These refi ned products are derived from crude oil, which generally contains some fraction of hydrogen sulphide.


During refi ning, sulphur levels are reduced. However, there is always a risk that H2

S monitors is advocated in the IGC (International Code for Ships


Carrying Liquefi ed Gases in Bulk) The IGC is relevant to LNG and LPG shipping, requirements for fi xed / sampling Systems are outlined. The Code states that gas detection equipment shall be installed to monitor the integrity of the cargo containment, cargo handling and ancillary systems. It adds that a permanently installed system of fi xed gas detectors with audible and visual alarms shall be fi tted in:


i. all enclosed cargo and cargo machinery spaces (including turret compartments) containing gas piping, gas equipment or gas consumers;


ii. other enclosed or semi-enclosed spaces where cargo vapours may accumulate, including inter barrier spaces and hold spaces for independent tanks other than Type C tanks;


iii. airlocks; iv. spaces in gas-fi red internal combustion engines; v. ventilation hoods and gas ducts;


Product transfer at refi ned products and crude terminal


vi. cooling/heating circuits; vii. inert gas generator supply headers; viii. motor rooms for cargo handling machinery.


In Section 13.6.3, the IGC confi rms that gas detection equipment shall be designed, installed, and tested in accordance with recognised standards and shall be suitable for the cargoes to be carried. Section 13.6.19 confi rms that every ship shall be provided with at least two sets of portable gas detection equipment that meet the requirement of 13.6.3 or an acceptable national or international standard. Section 13.6.20 explains that a suitable instrument for the measurement of oxygen levels in inert atmospheres should be provided.

New deals totalling over $1.3 M protect 1,000+ workers across Oman, Saudi Arabia and UAE


Blackline Safety Corp. have announced that they have secured new deals in the previous six months totaling more than $1.3 million with three of the world’s leading energy companies in Oman, Saudi Arabia and United Arab Emirates (UAE).


The oil and gas giants are purchasing a combined 1,200 G7c and 200 G7x portable gas detectors, 50 G7 EXO area gas monitors and 40 G7 Bridges to protect their workers at various sites across the Middle East. Several deliveries have already been completed, with the balance of the hardware and service revenue to be realized over the next year.


Blackline’s all-in-one solution for lone worker and gas detection improves frontline worker safety and


optimizes operations by providing access to real-time information—making the company uniquely positioned to seize the global connected worker market with a compound annual growth rate of 20 percent.


“These deals are completely new connected gas detection contracts. We didn’t go in and replace competitors’ products. Customers are asking for connected safety in the fi eld and remote locations, and Blackline Safety is the only provider that can fulfi ll this need with real-time visibility into what workers are experiencing on the job,” said Peter Attalla, Vice President, International Sales.


“Blackline has worked with our customers over the last two years to prove our technology in the region—and the feedback continues to be very positive. The reliability of our devices coupled with our real-time capabilities and our reporting suite, Blackline Analytics, set us apart. We started with piloting our lone worker solution, and now they are purchasing our full suite of gas detection products,” added Attalla.


This is the second time this year the company has announced major deals in the Middle East. In the fi rst—reported in January 2023—Blackline was named a preferred supplier for major energy company in a deal valued over $1 million.


Blackline’s growth in the Middle East isn’t limited to equipment purchases. The company has also seen their rental business accelerate, with high demand for G7c and G7 EXO devices in Oman and Saudi Arabia.


“The growth in the region in the last year alone demonstrates the increased traction we are gaining globally,” said Attalla. “Companies around the world want to make sure their workers are protected while on the job, wherever the job, and Blackline’s solutions are fi lling the need to ensure workers have the confi dence to get their job done safely and return home at the end of their day.”

New, hands-free thermal imaging for fi refi ghter safety applications


Dräger has launched the UCF FireCore, a hands-free thermal imaging camera that displays live-action imagery into the Dräger FPS 7000 full face mask. The UCF FireCore gives fi refi ghters continuous vision in the low- visibility, high-risk, and unfamiliar environments that emergencies often present. With IP67 certifi cation, the UCF FireCore is resistant to water and dust, with lithium-ion batteries guaranteeing safety over long durations. The batteries can be charged easily both in the fi re vehicle, and at the fi re station, prior to being deployed.


The camera can be fi tted to any model, shape or size of helmet through a simple bracket, and is fully detachable, allowing fi refi ghters to extend their vision in diffi cult-to-reach areas, and around corners, to enhance situational awareness and spot risks before they present further hazards. When mounted, the viewing angle can be fully adjusted, providing fi refi ghters with the fl exibility to adapt to emergency situations in a matter of seconds.


Near Field Communication (NFC) technology enables the camera to connect to the FPS in-mask display, or transfer the UCF FireCore from one helmet to another. This helps emergency personnel to pass on life-saving technology from one task force to the other – even at the scene of an emergency. This is achieved by holding the thermal imaging camera in close proximity to the in-mask display, before mounting on the helmet.


Liz Milward, Marketing Manager, Emergency and Rescue Services at Dräger Safety UK, says that the release of the UCF FireCore will speed up search and rescue missions and improve fi refi ghter orientation in the most diffi cult conditions: “With fl ames, smoke and darkness impairing vision in high-risk environments, improving situational awareness and enhancing fi refi ghter orientation is critical if we are to protect the lives of fi refi ghters in the most dangerous environments.
