 Trustindex verifies that the original source of the review is Google. Did the 5 day forklift training course and thought it was really good from start to finish. John was a great instructor, explained everything clearly and got the balance between theory and practical spot on.
The practical side was really well set up too, with plenty of different exercises and some good challenging setups like chicanes and tighter manoeuvres, so you were actually learning how to control the forklift properly rather than just going through the motions.
By the end of the week I felt confident that I could operate a forklift safely and properly. Would definitely recommend Rizon Training and John to anyone looking to do their forklift training.

Very knowledgeable, professional, and explained everything clearly in a way that was easy to understand. The session was engaging and well-structured, and it really helped build my confidence. The trainer created a positive and supportive environment throughout. Would definitely recommend to anyone looking for high-quality training.

Why this course is important

Scenarios for Use

Workers in areas where H2S may occur, such as wastewater treatment facilities, oil and gas sites or confined spaces
Contractors, site workers, and safety teams needing awareness of H2S risks and emergency response procedures

The Risk We Address

H2S is a highly toxic gas that can cause serious harm—even at low concentrations. It is colourless, heavier than air, and can quickly accumulate in poorly ventilated areas, making it difficult to detect without proper equipment. This course teaches participants to identify hazards, use detection methods correctly, and respond safely to prevent serious incidents.

Skills and Knowledge Gained

Participants will gain a clear understanding of H2S properties, common sources and potential health effects. The course covers correct use of detection equipment, breathing apparaus, safe exposure limits, emergency procedures, risk assessment practices, and basic permit-to-work requirements which are reinforced through practical exercises.

assessment type

Participants are required to complete a a short written assessment to demonstrate their understanding of H2S hazards, detection, and safe response techniques.

We wanted our supervisors, wherever they are located, to be able to join a leadership development programme that would leave them motivated, engaged and enthusiastic about their role and working with Fugro. The feedback from supervisors has been superb, with people asking to join the programme, in such high numbers that sometimes we have had to find ways to make sure everyone was accommodated.
